Question

Abox contains 3 blue, 2 white, and 5 red marbles. If a marble is drawn at random from the  box, then answer the questions from 1 to 5. 1. What is the probability that the marble will be white?  2. What is the probability that the marble will be red?​

Answer 1

Step-by-step explanation:

$Total \: number \: of \: marbles \: in \: a \: \\ bag = 3+2+5 = 10$

$1)$

$Number \: of \: favourable \: outcomes = 2 \\ </u></p><p><u>[tex]Number \: of \: favourable \: outcomes = 2 \\ Total \: number \: of \: outcomes = 10$

$We \: know \: that,$

$P(E) = \frac{number of favourable outcomes}{total number of outcomes}$

$</u></p><p><u>[tex]=> \frac{2}{10} = \frac{1}{5}$

$2)$

$Number \: of \: favourable \: outcomes = 5 \\ </u></p><p><u>[tex]Number \: of \: favourable \: outcomes = 5 \\ \: Total \: number \: o f \: \: outcomes = 10$

$We \: know \: that,$

$P(E) = \frac{number of favourable outcomes}{total number of outcomes}$

$</u></p><p><u>[tex]=> \frac{5}{10} = \frac{1}{2}$
