Answer:
a) 62
b) 31/45
Step-by-step explanation:
a) The table tells you there are 42 males, and 20 more females that study biology.
42 +20 = 62 . . . are male or study biology or both
__
b) Of the total of 90 people, 62 are male or study biology (or both). The probability that any person is in that category is ...
62/90 = 31/45 = P(male or biology)
Answer:
B. 12.5 feet below the surface of the water
Step-by-step explanation:
-20 + (-32.5) + 40
40 - 52.5
= -12.5 feet
= 12.5 feet below the water
12-4= 8 so divide 80 by ten and get 8
