Question

a spinner has 24 equal sectors, colured red, white or blue. The probability that the spinner shows white is 1/3. The probability that the spinner shows blue is 1/4. How sectors are red

Answer 1

the answer is 23.7142857143

Answer 2

Hey!!

Total number of sectors = 24
So, sum of blue, white and red sectors = 24

$probability \: of \: getting \: white = \frac{1}{3} \times \frac{8}{8} = \frac{8}{24} \\ no \: of \: white \: sectors = 8 \\ probability \: of \: getting \: blue = \frac{1}{4} \times \frac{6}{6} = \frac{6}{24} \\ no \: of \: blue \: sectors = 6 \\ no \: of \: red \: sectors \: = 24 - (8 + 6) = 24 - 14 = 10$

No of red sectors is 10.

Hope it helps!!
