Question

There are 9 white and 6 black marbles in a bag. Find the probability of picking each ball
randomly. Are the events equally likely? Give reasons.​

Answer 1

Answer:

• 9/15 is the probability getting a white marble.
• 6/15 is the probability getting a black marble.
• No, the events are not equally likely.

Step-by-step explanation:

Number of white marbles = 9

Number of black marbles = 6

Total number of marbles:

⇏ White marbles + Black marbles

⇏ 9 + 6

⇏ 15

Probability of picking a white marble

⇏ Favourable outcome/Total outcomes

⇏ 9/15

Probability of picking a black marble

⇏ Favourable outcome/Total outcomes

⇏ 6/15

9/15 > 6/15, No, events are not equally likely, As the number of white marble is is larger. the probability of getting a white marble is greater than the probability of getting a black marble
