Question

A pair of dice is thrown 4 times. If a double is condidered a success then find the probabilty of 2 succeses?

Answer 1

Answer:

Step-by-step explanation:

Total number of outcomes = 36

The possible doublets are (1, 1), (2, 2), (3, 3), (4, 4), (5, 5), and (6, 6).

Let p be the probability of success, therefore,

p =  

So, q = 1 - p =  

Since the dice is thrown 4 times, n=4

Let X denote the number of times of getting doublets in the experiment of throwing two dice simultaneously four times.

Therefore X can take the values 0, 1, 2, 3, or 4.

Thus, the probability distribution is:

X

0

1

2

3

4

P(X)
