Answer 1

Answer:

Step-by-step explanation:

p[red ball]=50/150=1/3

p[blue ball]=40/150=4/15

p[white ball]=60/150=2/5

Answer 2

The correct answer for 1) $\frac{1}{3}$, 2) $\frac{4}{15}$ and 3) $\frac{2}{5}$.

Given: Total balls = 150.

Red balls = 50 balls.

Blue balls = 40 balls.

White balls = 60 balls.

To Find: Probability of the ball drawn is 1) Red, 2) Blue and 3) White.

Solution:

1) Probability of the ball drawn is red P(R) = $\frac{Favorable outcomes }{Total outcomes}$.

P(R) = $\frac{Red balls}{Total balls}$

P(R) = $\frac{50}{150} =\frac{1}{3}$

2) Probability of the ball drawn is blue P(B) = $\frac{Favorable outcomes }{Total outcomes}$.

P(B) = $\frac{Blue balls}{Total balls}$

P(B) = $\frac{40}{150} =\frac{4}{15}$

3) Probability of the ball drawn is white P(W) = $\frac{Favorable outcomes }{Total outcomes}$.

P(W) = $\frac{White balls}{Total balls}$

P(W) = $\frac{60}{150} =\frac{2}{5}$

Hence, the probability of ball drawn is red is $\frac{1}{3}$ , blue is  $\frac{4}{15}$ and white is  $\frac{2}{5}$.
