Answer:
 =57.89%
Step-by-step explanation:
The total number of golf ball is 4+8+7 = 19
P (red or yellow) = number of red or yellow
               ------------------------------------
                total number of golf balls
              = 4+7
               -----
               19
             =11/19
Changing this to a percent means changing it to a decimal and multiplying by 100%
            = .578947368 * 100%
             =57.8947368%
Rounding to two decimal places
             =57.89%
The required probability is [tex]57.89\%[/tex]..
Important information:
- Number of red golf balls: 4
- Number of green golf balls: 8
- Number of yellow golf balls: 7
We need to find the probability of taking out a golf ball and having it be a red or a yellow golf ball.
Probability:
Total number of golf balls is:
[tex]4+8+7=19[/tex]
Number of red and yellow balls is:
[tex]4+7=11[/tex]
The probability of taking out a golf ball and having it be a red or a yellow golf ball.
[tex]P=\dfrac{\text{Number of red and yellow balls}}{\text{Total number of golf balls}}[/tex]
[tex]P=\dfrac{11}{19}[/tex]
Convert it into percent form.
[tex]P=\dfrac{11}{19}\times 100\%[/tex]
[tex]P=\dfrac{1100}{19}\%[/tex]
[tex]P=57.8947...\%[/tex]
[tex]P\approx 57.89\%[/tex]
Thus, the required probability is [tex]57.89\%[/tex].
