Can somebody explain in simple terms how to find probability involving the word "and"

In probability there is a very important distinction between the words AND & OR.

AND means that the outcome has to satisfy both conditions at the same time.

OR Means that the outcome has the satisfy one condition OR the other condition OR both at the same.

Idon’t actually know but have you asked google yet

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
