Probability has to do with the possibility that an event may or may not happen.

What is the probability?

The term probability has to do with the possibility that an event may or may not happen. The value of probability always ranges from zero to one.

Now;

Total number of fishes = 32 + 14 + 10 + 3 = 59

a) probability of catching a bass and then a carp = 32/59 * 10/59 = 320/3481

b) probability of catching two consecutive bull sharks= 3/59 * 3/59 = 9/3481

c) probability of catching  a fluke and then any different type of fish 14/59 * (32/59 + 10/59 + 3/59) = 14/59 * 45/59 = 630/3481

d) probability of catching  a bass, another bass, and a bull shark =  32/59 * 32/59 * 3/59 = 3072/205379
