Based on a sample survey, a principal claims that 7 out of 10 students like math. If there are 1300 students, how many would you predicted do NOT like math?

910

Step-by-step explanation:

70 percent of 1300 = 910

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
