Answer:
7/45.
Explanation:
The probability of getting blue on the first spin is 7/10, since there are 7 blue sections out of a total of 10 sections.
After the first spin, there will be 9 sections left, out of which 2 are gray and 7 are blue. The probability of getting gray on the second spin, given that the first spin was blue, is 2/9, since there are 2 gray sections left out of a total of 9 sections.
To find the probability of both events happening together (getting blue on the first spin and gray on the second spin), we need to multiply their individual probabilities:
(7/10) × (2/9) = 14/90
Simplifying this fraction by dividing both the numerator and denominator by 2, we get:
7/45
Therefore, the probability of the first spin landing on blue and the second spin landing on gray is 7/45.
