Question

what is the probability of a student owning a car that is not blue or green round to two decimal places

Answer 1

0.83

Explanation

The probability of an event is the number of favorable outcomes divided by the total number of outcomes possible

$P=\frac{favorable\text{ ourcomes}}{\text{total possible outcomes}}$

Step |

Let

$\begin{gathered} \text{favorable outcomes=car that is not blue or gre}en,\text{ so} \\ \text{favorable outcomes=}red\text{ cars+yellow cars+white cars+other} \\ \text{favorable outcomes=}40+29+26+14 \\ \text{favorable outcomes=}109 \end{gathered}$

now, the total outcomes is the total of cars

$\text{total outcomes=40+13+29+26+10+14=132}$

Finally, replace in the equation

$\begin{gathered} P=\frac{favorable\text{ ourcomes}}{\text{total possible outcomes}} \\ p=\frac{109}{132} \\ P=0.83 \end{gathered}$

so, the answer is 0.83
