Question

The probability of getting 53 sundays and not getting 53 sundays are the zeroes form a quadratic polynomial ​

Answer 1

in 4 years once we will get 53 sundays so its probability is 0.25 and the probability of not getting it is 0.75 so the quadratic eq becomes

$x {}^{2} - ( \alpha + \beta )x + \alpha \beta = 0 \\ {x}^{2} - (0.25 + 0.75)x + \frac{1}{4} . \frac{3}{4} = 0 \\ = > 16 {x }^{2} - 16x + 3 = 0$
