Question

A box contains 3 red, 4 green, and 3 yellow balls. If a ball is drawn at random, find the probability that the ball is red.A.4/10B.3/10C.6/10D.7/10

Answer 1

Given:

To get the probability that a ball picked is red, we use the formula for probability below,

`\text{Probability}=\frac{n\text{ umber of required outcome}}{n\text{ umber of total or possible outcomes}}`

Hence,

`\begin{gathered} \text{Probability}=\frac{n\text{ umber of required outcome}}{n\text{ umber of total or possible outcomes}} \\ \text{Probability}=\frac{n\text{ umber of red balls}}{\text{ total number of balls}} \\ \text{Probability}=(3)/(10) \end{gathered}`

Therefore, the probability that the ball is red is;

`(3)/(10)`

Hence, the correct answer is OPTION B.
