Answer:
30/40 or P(male ∣ fly)=43=0.75
Step-by-step explanation:
The condition is that the student chose to fly as their superpower. There were 40 total students in the sample who chose to fly, and 30 of them were male.
Superpower Male Female TOTAL
Fly 30 10 40
Invisibility 12 32 44
Other 10 6 16
TOTAL 52 48 100
P(male ∣ fly)= 30/40= 3/4=0.75
P(male ∣ fly)= P(male and fly)/ P(fly)
=30/100/40/100= 0.30/0.40= 3/4= 0.75
P(male ∣ fly)=3/4=0.75
Step-by-step explanation:
Joe's climbing rate is not constant
3 × 2 = 6
8 × 1.5 = 12
12 × 1.1666666667 = 14
Time when climber reaches 30ft is unknown because climbing rate is not constant
Zas's climbing rate is 2.5
2 × 2.5 = 5
4 × 2.5 = 10
12 × 2.5 = 30
At 12 seconds, Zas reaches 30 feet.
Stephen's climbing rate is 4
2 × 4 = 8
4 × 4 = 16
6 × 4 = 24
30 ÷ 4 = 7.5
7.5 × 4 = 30
At 7.5 seconds, Stephen reaches 30 feet.
The correct answer is 4/3
