ANSWER: 31.25%
Explaination:
Suppose (x+y) is the binomial distribution with 5 trials. Given that, probability of exactly two success in five trials of a binomial experiment in which the probability of success is 50%.
So, x = 0.5 and y = 0.5
The term
5C2*x²*y³ representing 2 successes and 3 failures.
Now find the value of this term.
5C2*(0.5)²*(0.5)³ = *
=10*0.03125
= 31.25%
Direct variation can be written as a proportion. Therefore, we can write:
Cross multiply to get:
4y=40
Divide by 4 on both sides to get that y=10.
