Question

A die is thrown 1000 times with the following frequency for the outcomes 1, 2, 3, 4, 5 and 6 as given below :

$\begin{array}{ccccccc}\text{Outcome}& 1& 2& 3& 4& 5& 6\\ \text{frequency}& 179& 150& 157& 149& 175& 190\end{array}$

(i) Find the probability of getting a 4 or a 6
(ii) Find the probability of getting a multiple of 3 [ 2 MARKS]

Answer 1

Solution:1 Mark each


Number of times a 4 or a 6 was rolled = 149 + 190 = 339
Probability = 339/1000 = 0.339
Number of times a 3 or a 6 was rolled = 157 + 190 = 347
Probability of rolling a multiple of 3 = 347/1000 = 0.347
