d) 0.17
Probability =
no. of favourable outcomes/total no. of outcomes
Why can't the answer be b) 17%?
bcoz (here - no. of outcomes = 100 & favourable outcomes= 17)
17/100 = 17% in terms of percentage
but 17/100 = 0.17 in terms of value
& probability can be expressed in % and fractions but not in decimals.
