Convert the percentages in decimals:
90/100 = 0.9, 20/100 = 0.2
Multiply the decimals:
0.9 times 0.2 is 0.18, or 18%
Greg has an 18% chance of being elected both positions.

Answer:
probability that Greg will be selected as the president of the sports club and will also be elected editor of the school magazine is 18%
Step-by-step explanation:
A: greg will be selected as president of the school sports club
P(A)=20%=0.2
B: greg will be elected editor of the school magazine
PB)=90%=0.9
A∩B: Greg will be selected as the president of the sports club and will also be elected editor of the school magazine
A and B are independent events
hence, P(A∩B)=P(A)×P(B)
= 0.2×0.9
=0.18
=18%
hence, probability that Greg will be selected as the president of the sports club and will also be elected editor of the school magazine is 18%
