In a class of 26 students, 15 of them like maths, 13 of them like English and 9 of them don't like Maths or English. Find the probability that a student chosen at random likes English but not Maths

0 0769

Step-by-step explanation:

Let x be the number of students that offer both subjects

15 - x + x + 13 - x + 9 = 26

-x + 37 = 26

-x = -11

x = 11

Number of student that offer english but not math = 13 - 11 = 2

The probability of english but not math = 2/26 = 0.0769

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
