The probability of choosing a black token from the bag is 31.25% and the probability of choosing a red token from the bag is also 31.25%.
What is probability?
Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
A bag contains 80 colored tokens. Of all the tokens in the bag, 25 are black and 5/16 are red.
- a. In percent form, the probability of choosing a black token.
There are total tokens are 80 in which black token are 25 black tokens. Thus, the probability of choosing black token is,
[tex]P=\dfrac{25}{80}\\P=0.3125\\P=31.25\%[/tex]
- b.In percent form, the probability of choosing a red token.
There are total 5/16 tokens in bag. Thus, the number of red tokens in bag is,
[tex]n=\dfrac{5}{16}\times80\\n=25[/tex]
Thus, the probability of choosing red token is,
[tex]P=\dfrac{25}{80}\\P=0.3125\\P=31.25\%[/tex]
Thus, the probability of choosing a black token from the bag is 31.25% and the probability of choosing a red token from the bag is also 31.25%.
