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

<h3>The equivalent expression is 6 + 6x</h3>
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
9 - (3 - 6x)
We have to find the equivalent expression
Use the distributive property,
a(b + c) = ab + bc
Therefore, from given expression,
Combine the constants, 9 - 3 = 6
Thus the equivalent expression is 6 + 6x
Answer:
29.095
Step-by-step explanation:
115 x 253 = 29095 mL
convert mL to Liters
Just do 29095 divided by 1000
Answer:
Equal to!
Step-by-step explanation:
2 x 1.08 is 2.16
(1.08/100) x 200 = 2.16
2.16 = 2.16
