<u>Answer:</u>
Two events, A and B, are independent. If P(A) = 0.3 and P(B) = 0.2.The value of P(A and B) is 0.06
<u>Solution:</u>
Given that P(A) and P(B) are two independent events which means the occurrence of one event does not affect the occurrence of another event.
Here we have to find out P(A and B)
When P(A) and P(B) are two independent events, then P(A and B) can be found out by,
P(A and B) = P(A)
P(B)
Given that P(A) = 0.3 and P(B) =0.2
P(A and B) = 0.3
0.2
P(A and B)= 0.06
Thus the value of P(A and B) is 0.06
A + b + c = 180
a = 2b
b = c + 4
Substitute the b equation into the a equation
a = 2(c + 4)
a = 2c + 8
Substitute equations a and b into the first equation
2c + 8 + c + 4 + c = 180
4c = 168
c = 42
Find the other angles using c
b = 42 + 4
b = 46
a = 2(42) + 8
a = 92
Therefore angle a is 92 degrees, angle b is 46 degrees, and angle c is 42 degrees.
