Two events, A and B, are independent. If P(A) = 0.3 and P(B) = 0.2, what is P(A and B)?

Flura [38]

Answer:0.06

Step-by-step explanation:

As the two events are independent

Therefore

$P(AandB) =P(A)\times P(B)$

As it is given that $P(A) = 0.3$ and $P(B) = 0.20$

Putting these value we get

$P(AandB) =0.3\times0.2 = 0.06$

$P(AandB)= 0.06$ is the required answer

The answer is y= -1x+8
Step-by-step explanation:
y=mx+b
m= -1
y-y=m(x-x1)
y-5=-1(x-3)
y-5=-1x+3
+5 +5

Please help me with this question! #10

Finger [1]

This is all about factoring. First of all, if we have the division of fractions, we can flip the second fraction and change the sign to multiplication. So now we have $\frac{7x+21}{ x^{2} +5x+6} * \frac{x+2}{x+6}$ . Now factor both the numerator and the denominator in the fraction on the left. Factor a 7 out of the numerator and factor completely the denominator to get this as a whole: $\frac{7(x+3)}{(x+3)(x+2)} * \frac{x+2}{x+6}$ . The (x+3) terms cancel each other out as do the (x+2) terms, leaving you simply with $\frac{7}{x+6}$
