Question

the probabilty of choosing a blue ball from a bag containing blue and white balls is 4/5.if the total number of balls ib a bag is 200, find the number of blue and white balls​

Answer 1

Step-by-step explanation:

Given:-

The probabilty of choosing a blue ball

from a bag containing blue and white

balls is 4/5. And the total number of

balls in a bag is 200.

To find:-

Find the number of blue and white balls

Solution:-

Total number of balls in a bag = 200

Total possible outcomes = 200

There are blue colur and white colour balls in the bag

The probability of choosing a blue ball from the bag = P(B) = 4/5

We know that

Probability of an event = Number of favourable outcomes/ Total number of possible outcomes

=> P(B)= (4/5)

Number of blue balls

=>(4×200)/5

=>800/5

=>160

Number of blue balls = 160

Number of white balls =

Total number of balls - Number of blue balls

=>200-160

=>40

Number of white balls = 40

Answer:-

Number of blue balls = 160

Number of white balls = 40

Used formula:-

• Probability of an event = Number of favourable outcomes/ Total number of possible outcomes

Answer 2

Answer:

No. of blue balls = 160

No. of white balls = 40
