$\begin{array}{cc}\text{Snack}& \text{Number of people}\\ \text{Pizza}& 42\\ \text{Sandwich}& 50\\ \text{Burger}& 74\\ \text{Ice cream}& 34\end{array}$

What is the probability that a person

(i) prefers ice cream?
(ii) does not prefer ice cream?

• A. 0.17, 0.83
• B. 0.46, 0.64
• C. 0.2, 0.8
• D. 0.3, 0.7

Answer 1

The correct option is A 0.17, 0.83

$Probability=\frac{No.offavourableevents}{Totalno.ofevents}$


Probability that a person prefers ice cream
$=\frac{34}{200}=\mathrm{0.17.}$

Probability that a person does not prefer ice cream = 1 – 0.17 = 0.83.
