The probability that no orange discs are selected is 0.1295 and the probability that exactly 2 discs with numbers ending in a 6 are selected is 0.0721.
<h3>How to calculate probability?</h3>
The probability that no orange discs are selected will be:
= 200C5 / 300C5
= 0.1295
The probability that exactly 2 discs with numbers ending in a 6 are selected will be:
= (30C2 × 270C3) / (300C5)
= 0.0721
The probability that exactly 2 orange discs with numbers ending in a 6 are selected will be:
= (100C2 × 290C3) / (300C5)
= 0.0092
The mean of the number of pink discs selected will be:
= np
= 5 × 1/3
= 5/3
The variance will be:
= 5 × 1/3 × 2/3
= 10/9 = 1.11
