Your answer would be C
if triangle efg is equal to hjk then it will still be equal the opposite way. The symmetric property tells us that both sides of the equal sign are equal no matter what side they are on.

Step-by-step explanation:
<h3>(1)</h3>
The probability of landing on the color gray ONCE
= 2/7
Since it is spun 35 times, the expected number of times that it lands on a gray will be
(2/7 × 35) = 10 times
<h3>(2)</h3>
The probability of landing on the color black ONCE
= 1/7
Since it is spun 105 times, the expected number of times that it lands on a black will be
(⅐ × 105) = 15 times
The formula is:
Expected value = (Number of spinning)×(probability of landing on a colour)
