Answers

Since you already answered the first question, I'll answer the other two

1. There are four aces and 52 cards. Just divide 4 by 52 to get 1/13, or about 7.69%.

2. If you mean the probability of choosing white from the handful, that's (15-10)/15, or 1/3 (33.33%). However, in the mixture itself (combined with the handful), that's 300/1500, or 20%.

What is this percent of change 40;72

Answers

Given:
Original or base : 40
New amount : 72

We need to find the difference of the new amount and the original amount

72 - 40 = 32

We then divide the difference by the original amount

32/40 = 0.80

We multiply the quotient by 100%

0.80 x 100% = 80%

The percentage of change is 80%
