Gail practices swimming for 1 and 1 fourth hours swimming every day how much time does she practice in a week

1 answer:

8 0

If Gail practises swimming for 1 and 1/4 hours a day, then in a week she'll do:

1 1/4 * 7 = 5/4 * 7 = 35/4 = 8 3/4 [hours]

In other words she'll practice 8 hours and 45 minutes a week (assuming that she's still practicing on weekends).

Answer:

The correct answer is 0.0330 and the events are independent.

Step-by-step explanation:

Total number of balls in Bill's golf bag = 17

Let A be the event of drawing a white ball and B be the event of drawing an orange ball.

Number of white balls Bill has in his bag is 9.

Probability of the event A in the first draw = $\frac{9}{17}$

Number of orange ball in Bill's bag is 1.

Probability of event B in the second draw = $\frac{1}{16}$

Thus total probability for Tim to tee off with a white ball and putt with an orange ball = $\frac{9}{272}$ = 0.0330

The above events are independent on each other.
