A: involved in a club

B: studied 4+ hours/day

We're given that P(A) = 35.7%, P(B) = 27.8%, and P(A or B) = 53.4%. We want P(A and B).

Use the inclusion-exclusion principle:

P(A and B) = P(A) + P(B) - P(A or B)

P(A and B) = 35.7% + 27.8% - 53.4% = 10.1%

In a beaded necklace 3/12, of the beads
Alexxandr [17]

Answer: 7/12 of the beads are blue and green

Step-by-step explanation: To make both denominators of fraction 3/12 and 1/3 equal, you have to change both denominators to the lowest common denominator. Since the LCD (lowest common denominator) is 12 you have to multiply 1/3 by 4 to make the two denominators match.

1/3 x 4/4= 4/12

Then to find the total fraction of both green and blue beads on the necklace, you simply have to add the two fractions together.

4/12+3/12= 7/12

hope this helps :)
