All the outcomes are 10 (possibilities)


To pull a quarter (total 3), its probability = 3/10 or 0.3

Now without putting the quarter back, the remaining total is now 9 (because one quarter was pulled out) so the probability of getting a penny is 2/9

But this is a conditional probability a) 1st pull a quarter & 2nd pull a penny

So the total probability is 3/10 x 2/9 =6/90 = 1/15 = 0.067

What figure has a perimeter of 22 units?
Sav [38]
Without knowing the shape selection you have i cant really say anything.  But with a square you wouldnt have any whole numbers, nor would a triangle give you whole number, than again no shape that i can think of would give whole numbers.
