Step-by-step explanation:
Weekdays Weekend
Male 50 10
Female 150 30
The males go to the park more often on the weekend.
This is false Males go more on the weekdays 50 vs 10
The females go to the park more often on weekdays.
True Females go on the weekdays 150 to 30
For the participants in the survey, gender affects which days of the week a person goes to the park.
False, they both go to the park more on the weekdays
Males 50 to 10 on the weekdays which simplifies to 5 to 1
Females 150 to 30 which simplifies to 150/30 to 30/30 or 5 to 1
It is equal
Answer:
What is P(A), the probability that the first student is a girl? (3/4)
What is P(A), the probability that the first student is a girl? (3/4)What is P(B), the probability that the second student is a girl? (3/4)
What is P(A), the probability that the first student is a girl? (3/4)What is P(B), the probability that the second student is a girl? (3/4)What is P(A and B), the probability that the first student is a girl and the second student is a girl? (1/2)
The probability that the first student is a girl is (3/4), likewise for the 2nd 3rd and 4th it's still (3/4). The order you pick them doesn't matter.
However, once you're looking at P(A and B) then you're fixing the first position and saying if the first student is a girl what's the probability of the second student being a girl.
0.15 as fraction or multiply 3/8 and 2/5
(12)2x=32
2x= 32/12
2x=8/3
I apologize I'm not sure where they get the 5. So I'm very interested in this answer as well.
