A man is known to speak truth 3 out of 4 times.He throws a die & reports that it is a six.Find the probability that it is actually a six.
A man takes a step forward with probability of 0.4 and backwards with probability of 0.6.Find probability that at the end of eleven steps, he is just one step away from the starting point..
In a game, a man wins a rupee for a six and loses a rupee for any other number when a fair die is thrown. The man decided to throw a die thrice but to quit as and when he gets a six. Find the expected value of the amount he wins/loses.
pls xplain the steps
A & B take turns in throwing two dice.The first to throw a sum 1o,being awarded.Show that if A has the first throw, their chances of winning is at the ratio of 12:11.
A die is thrown again and again until three sixes are obtained. Find the probability of obtaining the third six in the sixth throw of the die.?
pls xplain me the solution
A letter is known to have come either from LONDON or CLIFTON . On the envelope just two consecutive letters ON are visible . What is the probability that the letter has come from
(1) LONDON
(2) CLIFTON
twelve balls are distributed among three boxes ,find the probability that the first box will contain 3 balls .... and also explain how we solve these type of prblms ....and sum stategy to make strong probability
2 integers are selected at random from 1 to 11 . if the sum is even .find the probability that both numbers are odd
A and B throw a dice alternatively till one of them gets a ‘6’and wins the game. Find their respective probabilities of winning,if A starts first??P(A w ins)= P(S)+ P(FFS)+ P(FFFFS)=given below and so on.step 2 = 1/6/1-25/36 = 6/11 please tell me fast.how step 2 came
P(A w ins)= P(S)+ P(FFS)+ P(FFFFS)=given below
and so on.
step 2 = 1/6/1-25/36 = 6/11 please tell me fast.
how step 2 came
A bag contains 4 balls.Two balls are drawn at random, and are found to be white. What is the probability that all balls are white ?
A pair of dice is thrown 4 times. If getting a doublet is considered a success, find the probability of the number of successes and hence find its mean
three groups of children contain 3 girls and 1 boy : 2 girls and 4 boys :and 1 girls and 3 boys respectively. one children is selected at random from each group. find the chance that the three selected comprise 1 girl and 2 boys.
A biased die is twice as likely to show an even number as an odd number. The die is rolled three times. If occurrence of an even number is considered a success, then write the probability ditribution of number of successes. Also find the mean number of success.
