It's not possible for a number to not have any prime factors be cause the number will always be able to have the factor of 1 whcih is a prime number
Answer:
The value of P(A and B) is 1/10
Step-by-step explanation:
In case of independent events, the probability of one event doesn't depend on the probability of other events.
Therefore, for an independent events
P(A and B) = P(A) × P(B)
P(A and B) = 2/5 × 1/4
P(A and B) =2/20
P(A and B) =1/10
Therefore, the value of P(A and B) is 1/10
Answer:
17/20
Step-by-step explanation:
3/4 + 4/5 - 7/10
1. Find the LCD (Least Common Denominator). The LCD is 20.
2. 20/4=5. 5*3=15. So, 3/4 becomes 15/20.
3. 20/5=4. 4*4=16. So, 4/5 becomes 16/20.
4. 20/10=2. 2*7=14. So, 7/10 becomes 14/20.
5. Your new equation is 15/20 + 16/20 - 14/20.
6. Solve from left to right.
7. 15/20 + 16/20= 31/20.
8. 31/20 - 14/20= 17/20.
