) The probability of raining on a given day 0.15. Over a period of 9 days, what is the probability of raining in:
i) 2 days? (5 marks)
ii) 3 days? (5 marks)
iii) at least 3 days?

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

the answer is d on edge
