Answer 1

Answer:

a) 3/4

b) 1/3

Step-by-step explanation:

a) as there are four players and chance of a single person to not win is 3 which is our favourable outcome.

so the probability is 3/4.

b) in the second match one playes drops out. so total outcomes becomes 3 and favourable is still 1 so probability becomes 1/3 .
