Students majoring in psychology surveyed 200 of their fellow students about their dreams. The results of the survey are shown in the Venn diagram. Let B be the event that the participant dreams in black and white and let C be the event that the participant dreams in color.

What is the probability that a randomly selected participant dreams in black and white or color?

"Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Math to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution, where you will learn the possibility of outcomes for a random experiment. "

Probability of all black = 4/200=0.02

Probability of all white = 12/200=0.06

Probability of all other color = 10/200=0.05

So, probability that a randomly selected participant dreams in black and white or color =0.02+0.06+0.05=0.13

Hence, the probability that a randomly selected participant dreams in black and white or color = 0.13
