What was your last question, I might be able to help.
Step-by-step explanation:
The total number of people mentioned in this problem is 15. 15 will be the denominator for the probability in fraction form. The sum of the # of people that include lifeguards and managers will be the numerator.
Therefore, the probability that the person picked is either a manager or a lifeguard is 10/15 [because there are 2 managers and 8 lifeguards; 2 + 8 =10].
<u>Fraction form of probability: 10/15</u>
<u>Decimal form: 0.6 repeated</u>
<u>Percent form: about 66.67%</u>
The answer would be 8900
Reason: when you round to 2 significant figures you are trying to reduce the number to 2 digits and the rest will become 0 to indicate a place value
