An economist in Kenya argued that 3.5% of all SMES would file for bank loans next year. For a random sample of 100SMES estimate the probability that at least 3 will file bank loans next year

0.6841

Step-by-step explanation:

Given: Probability of all SMES would file for bank loans next year = 3.5% = 0.035

Sample size : n = 100

Binomial probability distribution formula :

The probability that at least 3 will file bank loans next year :

Hence, the required probability= 0.6841

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
