Question

The probability that an individual is left-handed is 0.11. In a class of 29 students, what is the probability of finding five left-handers? 0.11 0.117 0.000 0.172

Answer 1

Answer: First option is correct.

Explanation:

Since we have given that

probability that an individual is left handed = 0.11

Probability that an individual is not left handed = 1-0.11 = 0.89

so, we need to find the probability of finding five left handers.

We will use "Binomial distribution":

P(X=5)=
`^(29)C_5(0.11)^5(0.89)^(24)=0.11`

Hence, the probability of finding five left handers is 0.11.

Therefore, First option is correct.
