Ben has a 40% chance of being selected as the president of the school sports club and a 70% chance of being elected editor of the school magazine.
what is the probability that ben will be selected as the president of the sports club and will also be elected editor of the school magazine?

Probability of Ben for being selected as president of sport club and elected editor of the school magazine will be = 0.28

Step-by-step explanation:

Here given in the question is Ben has a chance of being selected as president of the school = 40% and a chance of being elected as editor of the school magazine = 70%

Therefore probability of two different events are

P(A) = 0.40

P(B) = 0.70

Now probability of happening both the events will be = P(A) × P(B) = 0.40×0.70 = 0.28

Therefore probability of happening of both the events will be = 0.28

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
