11-5=6
6 divided by 20
The probability that he hits will a bulls eye with at least one of his next three shots is 98.43%.
<h2><u>
Probabilities</u></h2>
Given that a marksman can hit a bull eyes from 100 m three times out of every four shots, to determine what is the probability that hits will a bulls eye with a least one of his next three shots, the following calculation must be performed:
- Probability of failure: 0.25
- 0.25 x 0.25 x 0.25 = X
- 0.0156 = X
- 1 - 0.0156 = X
- 0.9843 = Chance
Therefore, the probability that he hits will a bulls eye with at least one of his next three shots is 98.43%.

<h3>
Solution (a):</h3>
<em>~Let's change 9.9² to 10² since we have to estimate.~</em>
<u>We know that:</u>
- 10² = 100
- Given expression: 9.9² × 1.79
<u>Solving the expression:</u>
- 9.9² × 1.79
- => 10² × 1.79
- => 100 × 1.79
- => 179
The estimated value of 9.9² × 1.79 is 179.
<h3>Solution (b):</h3>
<em>~Let's change √97.5 to √100 and 1.96 to 2</em> <em>since we have to estimate.~</em>
<u>We know that:</u>
- √100 = 10
- Given expression: √97.5 ÷ 1.96
<u>Solving the expression:</u>
- √97.5 ÷ 1.96
- => √100 ÷ 2
- => 10 ÷ 2
- => 5
The estimated value of √97.5 ÷ 1.96 is 5.
M = 72
Your main goal in this equation is to isolate m or in other words leave m alone in one side of the equality.
All you need to do is multiply 4 in both sides for you to eliminate the denominator attached to m.
Saying this,
(M/4)(4) = (18)(4)
M = 72
