A company that explores for oil in the ocean is considering two new sites, A and B. The exploration will take the entire year. The company estimates the probability of finding oil is 0.48 at site A and 0.31 at site B. The sites are far enough apart so that whether or not oil is found at one site, is independent of its being found at the other. Required:
a. Find the probability that oil is found at both sites.
b. Find the probability that oil is found at only one of the sites.

im with everythinglos so yeahhhhh

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
