To find how many kids went swimming given that there were 25 kids in total and 40% of them went swimming, you must multiply the percent by the whole: 40%*25
Before you do this, first convert the percent to a decimal: 40%=0.40
Now, multiply your expression: 0.40*25 0.40*25=10
Therefore, your final answer would be that 10 out of the total 25 kids went swimming.
The probability is (1/6)^5 power. Since the locks are independent of each other, you can multiply the probabilities together. There are 6 possible numbers for each lock and there are 5 locks. So the probability is (1/6)^5 power.<span />
