Answer: Question 10 Total no of outcomes – 1,2,3,4,5,6 favourable outcomes – 3,4,5,6 . let the probability of getting a number greater than 2 be p(A) p(A) = No of favourable outcomes / Total no of outcomes = 4/6 = 2/3 Question 11 r – 5cm h – 6cm volume of cone – 1/3πr²h = 1/3 ×22 / 7 × (5)² × 6 = 3300/ 7 ×3 = 1100 / 7 =157.14285714 cm³ Reply
Answer:
Question 10
Total no of outcomes – 1,2,3,4,5,6
favourable outcomes – 3,4,5,6 .
let the probability of getting a number greater than 2 be p(A)
p(A) = No of favourable outcomes / Total no of outcomes
= 4/6
= 2/3
Question 11
r – 5cm
h – 6cm
volume of cone – 1/3πr²h
= 1/3 ×22 / 7 × (5)² × 6
= 3300/ 7 ×3
= 1100 / 7
=157.14285714 cm³
Answer:
question 10 = 2/ 3 answer
