Answer:
A. is the probability that a student randomly selected from a class of 60 students will be a male who has brown hair
B. For this case we will complete the table part by part.
Step by step solution:
First row:
Snake = Rabbit = 4
Rabbit = Not Snake = 18
Total = 4 + 18 = 22
Second row:
Not rabbit = Snake = 11
Not rabbit = Not Snake = 26
Total = 11 + 26 = 37
Third row:
Total = 4 + 11 = 15
Total = 18 + 26 = 44
Total = 59
