It is 5/11. You have to input 4 as x.
Yes that is a function
Explanation: to figure out it’s a function draw vertical lines if one line goes through two lines then it’s not a function
We need to find the probability of atleast one failure in 5 trails
Probability of success = 30% = 3/10
The opposite meaning of atleast one failure is all success (no failures)
Probability of (atleast one failure ) = 1- Probability ( success)
First we find probability of success
Formula for binomial distribution
All success so n=5, r=5, p= 3/10, q= 1-p = 7/10
Probability (success) =
=
Probability (atleat one failure) = 1 -
= 0.92224
= 92.2%
