Answer:
C. 1/9
Step-by-step explanation:
Assuming the selections are independent, their joint probability is the product of the probabilities of the individual events.
P(pink square) = (# pink squares)/(# squares) = 16/60 = 4/15
P(red or blue round) = (#red or blue rounds)/(# rounds) = 15/36
Then the joint probability is ...
P(defined event) = (4/15)(15/36) = 4/36 = 1/9

Answer:
132 and 88
Step-by-step explanation:
If there are 20% more boys than girls, then this means that the total percentage of boys us 60% and girls is 40%.
0.6 * 220 = 132
0.4 * 220 = 88
There are 132 boys and 88 girls in year 9
0.3(3 - 0.5)
= 0.3(2.5)
= 0.75
