Answer: There is a probability that a club member picked randomly is female, given that the person prefers swimming on weekends is 40%.

Step-by-step explanation:

Let E₁ be the event that members prefer swimming on weekends.

Let E₂ be the event that members prefer swimming on weekdays.

Let A be the event that the members are female.

Probability that members prefer swimming on weekends P(E₁) = 25%

Probability that members prefer swimming on weekdays P(E₂)= 75%

Probability that members prefer swimming on weekends and are female PA∩E₁)= 10%

Probability that members prefer swimming on weekdays and are female P(A∩E₂) = 55%

Using Conditional theorem, we will find the probability that a member is female given that the the person prefers swimming on weekends.

P(A\mid E_1)=\dfrac{P(A\cap E_1)}{P(E_1)}\\\\P(A\mid E_1)=\dfrac{10}{25}\\\\P(A\mid E_1)=0.4\\\\P(A\mid E_1)=0.4\times 100\%=40\%

Hence, there is a probability that a club member picked randomly is female, given that the person prefers swimming on weekends is 40%.

Answer:

Make coordinates with this table.

Step-by-step explanation:

What I think from these tables is that you can make coordinates with these points. Here are the instructions for you to follow-

  1. See the "y" and "x". These are the axis. So make coordinates with these. Ex- (0,3), (1,5) and so on
  2. Plot these coordinates in a graph paper.
  3. After plotting them, you might find the shape it made.

I hope it helps you.

Leokris [45]

Answer:

boys + girls =  45  -------(1)

There boys 17 more than girls, boys = girls + 17  ----------(2)

substitute (2) in (1)

girls + 17 + girls = 45

2 x girls + 17 = 45

2 x  girls = 45 - 17

2 x girls = 28

girls = 14

substitute in (2): boys = girls + 17 = 14 + 17 = 31

option D
