Answer:
52
Step-by-step explanation:
<u>Spinner A</u>
- Probability of red = 0.5,
- Probability of blue = 0.5
<u>Spinner B</u>
- Probability of red = 0.6,
- Probability of blue = 0.4
<u>Probability of both A and B land on red: </u>
<u>Number of attempts to get outcome of 84 red on both spinners is:</u>
<u>Probability of both spinners land on blue:</u>
<u>Estimated number of both spinners land on blue:</u>
