Artie has a book of short stories. the number of each time of short story is shown below. •6 science fiction stories •4 adventure stories • 3 historical stories • 2 sports stories he selects one short story at random. what is the probability that the story artie selects is either a science fiction story or an adventure story?

Probability of selecting either A or B P(A∩B)=2/3.

Step-by-step explanation:

Total number of story books=6+4+3+2=15

Let A be the event of selecting science fiction story

then its probability P(A)=number of science stories/total stories=6/15

Now let B be the event of selecting adventure story P(B)=number of adventure stories/total stories

=4/15

thus Probability of selecting either A or B P(A∩B)=P(A)+P(B)=6/15+4/15=10/15=2/3.

step-by-step explanation: yes

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
