Answer:
The probability that Actuary Rahul examines fewer policies that Actuary Toby = 0.2857
Step-by-step explanation:
It is said that Actuary Rahul examines a low risk policy
Probability of a low risk policy having a claim = 10% = 0.1
Actuary Toby examines high risk policy
Probability of a high risk policy having a claim = 20% = 0.2
Let the number of policies examined by actuary Rahul before he finds a claim and stop be n
Probability that actuary Rahul examines exactly n policies = 
Probability that Toby examines more than n policies = 
Since the claim statuses of policies are mutually independent, the probability that both events happen simultaneously = 
probability that both events happen simultaneously = 
The probability that Actuary Rahul examines fewer policies that Actuary Toby =
= 
The probability that Actuary Rahul examines fewer policies that Actuary Toby = 0.2857
Answer:
46 mph and 61 mph
Step-by-step explanation:
Distance=speed*time
Let speed of one bus be x and another x+15
After 3 hours
First bus would have traveled 3x while second bus 3(x+15)=3x+45
Total distance= 3x+3x+45=6x+45
6x+45=321
6x=321-45=276
x=276/6=46 mph
x+15=46+15=61 mph
√8
for the equations of circles: x²+y²= (radius)²
Thirty-seven point nine hundredths hope this helps :))
Wait I know u still need the answer or not anymore
