Question

What is the probability of getting ‘4’ as outcome?

(a) 0.16

(b) 0.158

(c) 0.156

(d) 0.131

This question was addressed to me in a job interview.

My query is from Probability & Experimental Approach in division Probability of Mathematics – Class 9

Answer 1

Correct option is (d) 0.131

For explanation I would say: We can see from the table that we get ‘4’ 79 times out of 500 trials.

Therefore, probability of getting ‘4’ as outcome = \(\frac{Event \,of \,occurence \,of \,getting \,’4′}{Total \,number \,of \,trials}\)

= \(\frac{79}{500}\)

= 0.158.
