Answer:
7.3%
Step-by-step explanation:
Let M = Maths
E = English
P(M ∪ E) = P(M) + P(E) - P( M ∩ E)
From the question:
P(M ∪ E) = 35.7%
P(M) = 18%
P(E) = 24%
P( M ∩ E) = unknown
35.7% = 18% + 24% - P( M ∩ E)
35.7% = 42% - P( M ∩ E)
P( M ∩ E) = 42% - 35.7%
P( M ∩ E) = 7.3%
Therefore, the probability that a student who receives an A in Math course will also receive an A in English course is 7.3%.

Since 1290 can be represented as 1290. we know that the decimal was moved to the right twice.
Answer:
Probablity of getting six in at most three roll= 0.199.
Step-by-step explanation:
Given: Dice rolled at most 3 times untill a 6 occurs.
First, finding the probablity of getting 6 in a dice if rolled once.
Probablity=
We know, dice have six side, therefore, total number of event will be 6.
∴ Probablity of getting six in one roll=
As given, Dice is rolled at most 3 times.
Now, finding the probablity of getting 6 in a dice if rolled 3 times.
∴ Probablity of getting six in three roll=
⇒ Probablity of getting six in three roll=
Taking LCD 216
⇒Probablity of getting six in three roll=
⇒Probablity of getting six in three roll=
∴Probablity of getting six in three roll=0.199
Answer:
D
Step-by-step explanation:
Given
- 8 < 4 ( add 8 to both sides )
< 12
Multiply both sides by 4 to clear the fraction
j < 48 → D
