Answer:
Total # of marbles: 10
# of red marbles: 7
Probability of choosing a red marble out of 10 marbles: 7/10
Then in the second round, you replace that marble so you still have a total of 10 marbles and 7 of them will still be red: 7/10
Multiply...
7/10 x 7/10 = 49/100
PROBABILITY: 49/100 (or 49%)

Answer:
Total people on the tour will be: 105 people
Step-by-step explanation:
- Total people on a mountain trail = 125
Given that 84% of the people on the trail are on a hiking tour.
We need to determine how many people are on the tour.
- All we need is to multiply 84% or 0.84 by 125.
i.e.
People are on the tour = 84% × 125
= 84/100 × 125
= 0.84 × 125
= 105 people
Therefore, total people on the tour will be: 105 people
