Question

A standard number cube is tossed. Find the following probability. P(greater than 4 or even)

Answer 1

Let:

A = Get a number greater than 4

B = Get an even number

The probability is given by:

$P(E)=\frac{m}{n}$

Where:

m = Number of favourable outcomes

n = Total number of outcomes

So:

$\begin{gathered} P(A)=\frac{2}{6}=\frac{1}{3} \\ P(B)=\frac{3}{6}=\frac{1}{2} \\ so\colon \\ P(A\cup B)=\frac{1}{3}+\frac{1}{2}=\frac{5}{6}\approx0.833 \end{gathered}$

Answer:

0.833
