The ODDS that the dart hits a date that is a prime number are 1:1
Step-by-step explanation:
Odds:
An odd is writen as:
Number of desired outcomes: Number of undesired outcomes.
In this question:
April has 30 days, 15 of which are prime numbers and 15 of which are odd numbers.
So the odds are:
15:15
Simplifying by 15
1:1
The ODDS that the dart hits a date that is a prime number are 1:1
 
        
             
        
        
        
Answer:
0.97
Step-by-step explanation:
Given that a homeowner has two smoke detector alarms installed, one in the dining room (adjacent to the kitchen) and one in an upstairs bedroom (above the kitchen). If cooking produces smoke in the kitchen, the probability of setting off the dining room alarm (D) is .95. The probability of setting off the bedroom alarm (B) is .40.
Both alarms are independent of each other.
Probability for smoke detection=P(any one alarm rings)
=P(Kitchen alarm sets off)+P(bed room alarm sets off)-P(Both sets off)
Since both are independent
P(Both) = 
Probability for smoke detection
= 0.95+0.40-0.38
=0.97
