A bag contains 12 red marbles, four black marbles, four purple marbles, and two pink marbles. What is the probability of selecting a black marble

4/22 chance of getting a black marble.

Step-by-step explanation:

Nick will get £16; Peter will get 60 sweets

Step-by-step explanation:

Angad and Nick win some money and share it in the ratio 2:1. The total ratio is:

2 + 1 = 3

Let the total amount shared be x.

Angad gets £32. This implies that:

2/3 * x = 32

=> 2x = 32 * 3 = 96

x = 96 / 2 = £48

Therefore, Nick will get:

1/3 * 48 = £16

Sushil, Alex and Peter share some sweets in the ratio 1:1:4. The total ratio is:

1 + 1 + 4 = 6

Let the total sweets shared be x.

Sushil gets 15 sweets. This means that:

1/6 * x = 15

x = 15 * 6 = 90 sweets

Therefore, Peter will get:

4/6 * 90 = 60 sweets
