Question

bA wheel with6 equal parts has 2 parts with a single dots. 1 part with 2 dots, 1 part with 3 dots and 2 parts with no dots. What is the probability that after spinning the wheel, the arrow will come to rest on the following parts?
(i) Part with a single dot
(ii) Part with 2 dots
(iii)Part with 3 dots
(iv)Part with no dots

Answer 1

1. Part with single dot = 2/6 = 1/3
2. 1/6
3. 1/6
4. 2/6 =1/3

Answer 2

Given : A wheel with 6 equal parts has 2 parts with single dots. 1 part with 2 dots, 1 part with and 2 parts with no dots.

To Find : probability that after spinning the wheel, the arrow will come to the rest of the following parts.

(i). Part with a single dot

(ii). Part with 2 dots

(iii). Part with 3 dots

(iv). Part with no dots​

Solution:

n(S) = 6  

A = Part with a single dot

n(A) = 2

P (A) = 2/6 = 1/3

B = Part with  two dots

n(B) =1

P (B) = 1/6 = 1/6

C = Part with three dots

n(C) =1

P (C) = 1/6 = 1/6

D = Part with no dots

n(D) = 2

P (D) = 2/6 = 1/3
