A bag contains 15 black, 17 green, 22 pink, and 29 yellow tokens. You pick one token at random.

Find the probability that it is yellow or black.

[tex]\[ P(\text{yellow or black}) = \][/tex]

[tex]\[ \square \][/tex]

Simplify your answer completely.



Answer :

To find the probability of picking a yellow or black token from a bag containing various colored tokens, follow these steps:

1. Calculate the Total Number of Tokens:
The bag contains:
- 15 black tokens
- 17 green tokens
- 22 pink tokens
- 29 yellow tokens

Adding these together gives the total number of tokens:
[tex]\[ 15 + 17 + 22 + 29 = 83 \][/tex]

2. Determine the Favorable Outcomes:
The favorable outcomes are the scenarios where you pick either a yellow or a black token.
- Number of yellow tokens: 29
- Number of black tokens: 15

So, the total number of favorable outcomes is:
[tex]\[ 29 + 15 = 44 \][/tex]

3. Calculate the Probability:
The probability of an event is given by the ratio of the number of favorable outcomes to the total number of outcomes.
[tex]\[ P(\text{yellow or black}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{44}{83} \][/tex]

The probability of picking a yellow or black token from the bag is:
[tex]\[ P(\text{yellow or black}) = \frac{44}{83} \approx 0.5301204819277109 \][/tex]

This fraction cannot be simplified further, so the answer remains as:
[tex]\[ P(\text{yellow or black}) = \frac{44}{83} \][/tex]
