Question

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

$\begin{array}{cc}\text{Outcome}& \text{Frequency}\\ 1& 165\\ 2& 175\\ 3& 180\\ 4& 150\\ 5& 145\\ 6& 185\end{array}$

What is the probability of getting 2 or 4?

• A. 0.515
• B. 0.245
• C. 0.325
• D. 0.455

Answer 1

The correct option is C

0.325

Number of times 2 or 4 appears when a die was rolled = 175 + 150 = 325

Total number of times a die is thrown = 1000

Probability of getting a 2 or a 4 $=\frac{\text{number of times 2 or 4 appears}}{\text{total number of times a die is thrown}}$

$\Rightarrow \text{Probability}=\frac{325}{1000}=0.325$
