Answer:
So minute hand will rotate
in half an hour
Step-by-step explanation:
In one hour minute hand of clock rotate about 360°
So in half an hour minute hand clock rotate 
We have to find how many minute hand rotate in radian
For conversion of degree to radian we have to multiply with 
So 
So minute hand will rotate
in half an hour
Answer:
2/21
Step-by-step explanation:
17/21 -(3/7 + 2/7)
First you add
=17/21 - (5/7)
Then you want to subtract
=2/21
Answer:
P'(C) = 0.98
Step-by-step explanation:
Given that,
P(C) = 0.02 (The probability of getting C)
We need to find the complement of P(C) i.e. P'(C).
We know that,
P(C)+P'(C)=1
P'(C) = 1-P(C)
= 1-0.02
= 0.98
So, the complement of P(C) is equal to 0.98.
