ONLY ANSWER IF YOU HAVE SOLUTION OR ELSE U WILL BE REPORTED! In a group of students, 50% of the students were taking statistics subject, 30% economics and 10% both the subjects. What is the probability that a student was taking neither statistics nor
economics?
a) 30% b) 90%
c) 70% d) None of these

Solution with som explanation

a) 30%

Step-by-step explanation:

50% of the students were taking statistics subject, 30% economics and 10% both the subjects.

The probability a student takes only statistics = 50% - 10% = 40%

The probability a student takes only economics = 30% - 10% = 20%

The probability a student was taking neither statistics nor  economics = 100% - (40% + 20% + 10%)

The probability a student was taking neither statistics nor  economics = 30%

radius= sqrt2/2

step-by-step explanation:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
