Probability of winning a grand prize is 1/10
Probability of winning a basic prize is 11/20
What is the probability of two independent events?
If A and B are two independent events, then P(A and B) = P(A) * P(B).
If Events A and B are independent, the probability that either Event A or Event B occurs is: P(A or B) = P(A) + P(B) - P(A and B).
Solution:
P(A) = no. of A / total possibility
= 4/10
P(B) = no. of 1's/total possibility
= 3/12
= 1/4
Now,
To win a grand prize you need an "A" and "1" .
∴ P(A and B) = P(A) × P(B)
= 4/10 × 1/4
P(A and B) = 1/10
Now ,
To win a basic prize you need to spin an "A" or a "1"
∴ P(A or B) = P(A) + P(B) - P(A and B)
= 4/10 + 1/4 - 1/10
= 3/10 + 1/4
∴ P(A or B)= 11/20

Answer:
x= 11
y= -2
Step-by-step explanation:
8y + 27 =x
3(8y+27) + 7y =19
24y + 81 + 7y =19
31y + 81 =19
<u> -81 -81</u>
<u>31y</u> = <u>-62</u>
<u>31 31 </u>
y = -2
-x + 8(-2) = -27
-x - 16 = -27
<u> +16 +16 </u>
-x = -11
x= 11
