Answer:

Step-by-step explanation:

P(A) = 144/200  = 0.72

P(B) = 141/200  = 0.705 = 0.71

The two probabilities are similar but different. From the table, a large number of students who play guitar are also left-handed: 116. So the two probabilities are NOT independent - if u are left-handed, u are more likely to play guitar n vice versa.

Answer:

Step-by-step explanation:

P(A) = Probability of a student knowing how to play guitar

= no. of students who know how to play guitar / total no. of student

= 144/200

= 0.72

P(B) = Probability of a student is left-handed

=  no. of students who is left-handed / total no. of student

= 141/200

= 0.705

P(A) and P(B) are calculated to be two real numbers and do not depend on each other. So event A and B are independent.

Answer:

It was a rainy day , but Joan and I had planned a trip. Joan wanted to go to the beach for a swim. I wasn't sure if we should go.

"I think we should wait a little longer , at least until the rain shows some signs of slowing down," I suggested.

"We can't swim without getting wet anyway," replied Joan, questioning my choice of swimsuit , the one my mom had bought at a secondhand store.

A box of 25 light bulbs is shipped to a hardware store.when it arrives,four of the bulbs are broken.predict the number of broken
anyanavicka [17]
First you need to divide 125 / 25 which is 5 then you do subtraction 21 x 5 which is 105, then you subtract again 125 - 105 which is 20, 20 light bulbs will be broken. Or you could have just multiplied 5 by 4 which is the amount of light bulbs that were broken which is a lot easier...
