Scott bought three bags of candy with 75 pieces in each one. He plans to divide all the candy evenly among seven friends. How ma
Katyanochek1 [597]
The answer will be 75 divided by 7.
I know this because if Scott wants to give the same amount of candy to seven friends, he will have to divide the total amount of candy by the number of friends.
75/7 is 10 r 5. (We can solve this in our head because we know 7x10 is 70 and 70+5 is 75.) 
The remainder is the amount he will have left. 
R=5
Scott will have 5 pieces left. 
Hope I helped! ;)

Two card are pulled from a normal deck of 52 cards, without replacement.
8090 [49]

Answer:

The probability that both cards that are drawn are hearts is 1/17.

Step-by-Step-Explanation:

First off, know that there are 13 heart cards in the deck of 52 cards. Therefore, the chance of pulling a single heart card is 13/52. Let's say we do pull a heart card. Since there is no replacement for the heart card taken out of the deck, we now have 12 heart cards out of a deck of 51 cards. The chance of pulling out a heart card in now 12/51. To find the probability that both cards drawn out are hearts, multiply the two fractions together: (13/52)⋅(12/51)=156/2652=1/17.

<h2></h2><h2>So hence, your answer is 1/17</h2>
