Carl has a piece of toast that has jelly on one side, and he dropped it twice. both times, it landed with the jelly side up. if he drops it 2 more times, what is the probability that it will have landed jelly side up a total of 3 times? (a) 1/4(b) 1/3(c) 1/2(d) 2/3

Option A -

Step-by-step explanation:

Given : Carl has a piece of toast that has jelly on one side, and he dropped it twice. Both times, it landed with the jelly side up. If he drops it 2 more times.

To find : What is the probability that it will have landed jelly side up a total of 3 times?

Solution :  

Carl has a piece of toast which is two sided.

Probability of success is

He drop the piece 4 times so n=4

The probability that it will have landed jelly side up a total of 3 times is given by binomial probability distribution.

i.e.

Here, r=3

Therefore, The probability that it will have landed jelly side up a total of 3 times is

So, Option A is correct.
