Jean bought a bag of candy that contained red candies, green candies, and brown candies. some candies are marked with a smile, and others are not marked. the probabilities are displayed in the table below: red green brown smile 0.10 0.30 0.10 no smile 0.20 0.15 0.15 if a random candy is chosen from this bag, what is the probability that the candy was red or had no smile?

 0.60

Step-by-step explanation: A:candy is red

                         P(A)=0.10+0.20=0.30

                                     B:candy had no smile

                         P(B)+0.20+0.15+0.15=0.50

                      A∪B:candy is red or had no smile

                     P(A∪B) we have to find

                     A∩B:candy is red and had no smile

                   P(A∩B)=0.20

               P(A∪B)=P(A)+P(B)-P(A∩B)

             P(A∪B)=0.30+0.50-0.20

                          = 0.60

hence, probability that candy was red or had no smile=0.60
