Suppose that E and F are two events and that Upper P (Upper E and Upper F )equals0.3 and Upper P (Upper E )equals0.5. What is Up

m_a_m_a [10]

Answer:

$P(\frac{F}{E}) =\frac{0.3}{0.5} =0.6$

Step-by-step explanation:

Step 1:-

Suppose that E and F are two events and that P(E n F) = 0.3

also given P(E) =0.5

Conditional probability:-

if E₁ and E₂ are two events in a Sample S and P(E₁)≠ 0, then the probability of E₂ , after the event E₁ has occurred, is called the Conditional probability

of the event E₂ given E₁ and is denoted by

$P(\frac{F}{E}) = \frac{P(EnF)}{P(E)}$

$P(\frac{F}{E}) =\frac{0.3}{0.5} =0.6$

Find he slope of the following equation for a line: 12x-4y=16

Annette [7]

12x-4y=16
Isolate Y:
Subtract 12x from both sides
-4y=-12x+16
Divide by -4
y=3x-4
Therefore the slope is 3

How many different ways can four team members from the group of fifteen be lined up for a photograph?

damaskus [11]

Answer:

32760

Step-by-step explanation:

This is a permutation of 15 objects taken 4 at a time. To calculate this, we use the formula:

$_nP_r=\frac{n!}{(n-r)!}$

In our case, n is 15 and r is 4:

$_{15}P_4=\frac{15!}{(15-4)!}=\frac{15!}{11!}=32760$
