Answer:
<h2>

</h2>
Step-by-step explanation:
The probability of occurring the event A is  .
.
The probability to occur the event B is  .
.
It is also given that the events are independent that is they do not depends on each other.
So, the probability of occurring both the events simultaneously can be get by simply multiplying the probabilities of both the events.
Hence, the probability is ![\frac{1}{[tex]57times23](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Btex%5D57times23) }[/tex] =

Answer:
0.04,0.25.0.52
Step-by-step explanation:
Given that you throw a dart at a circular target of radius 10 inches. 
Assuming that you hit the target and that the coordinates of the outcomes are chosen at random, 
 probability that the dart falls 
(a) within 2 inches of the center 
Here favourable region has area of a circle with radius 2 inches and sample space has area of 10 inches
Prob = 
 (b) within 2 inches of the rim.
For within two inches from the rim we have to select area of the ring i.e. area of big circle with 10 inches - area of smaller circle with 10-2 inches
Prob= 
c) within I quadrant
area of I quadrant / area of circle=0.25
d) within I quadrant and within 2 inches of the rim
= I quadrant area + 2 inches ring area - common area
= 
 
        
             
        
        
        
7 / 8 = 0.875
It is a terminating decimal because the decimal has a finite amount of numbers.
