Question

1)There are fourteen shirts in your closet, four blue, five green, and five red. You randomly select one to wear. It is blue or green2)a magazine contains for teen pages.you open to a random page. The page number is eight to ten.find the probability

Answer 1

Given:

Total number of shirts is, N= 14.

Number of blue shirts is, n(b) = 4.

Number of green shirts is, n(g) = 5.

Number of red shirts is, n(r) = 5.

The objective is to find the probability of randomly selecting a blue shirt or green shirt.

The required probability ca be calculated as,

$\begin{gathered} P(\text{blue or gr}een)=P(blue)+P(green) \\ =\frac{n(b)}{N}+\frac{n(g)}{N} \\ =\frac{4}{14}+\frac{5}{14} \\ =\frac{9}{14} \end{gathered}$

Hence, the probability of randomly selecting a blue shirt or green shirt is 9/14.
