Find the missing probability.<br> P(A) = 0.4; P(B) = 0.7; P(A or B)<br> ; P(A and B) = 0.3
solong [7]

Given:

P(A)=0.4, P(B)=0.7, P(A\text{ and }B)=0.3

To find:

The value of P(A\text{ or }B).

Solution:

We know that,

P(A\text{ and }B)=P(A\cap B)

P(A\text{ or }B)=P(A\cup B)

It means, we have P(A)=0.4, P(B)=0.7, P(A\cap B)=0.3 and we need to find the value of  P(A\cup B).

P(A\cup B)=P(A)+P(B)-P(A\cap B)

P(A\cup B)=0.4+0.7-0.3

P(A\cup B)=1.1-0.3

P(A\cup B)=0.8

Therefore, the value of P(A\text{ or }B) is 0.8.

What is the slope of the line that passes through the points (-8, -3) and
aleksklad [387]

Answer:

slope of the graph is

\frac{ - 1}{4}

Step-by-step explanation:

slope of a graph = (y2 - y1) / (x2 - y1)

  • 1 - (-3) / ( -24 - ( -8 ) )
  • 1 + 3 / -24 + 8
  • 4 / -16
  • 1 / -4
  • -1 / 4

hence the slope of the graph is

\frac{ - 1}{4}

i hope it helped...

Brums [2.3K]

1 ton = 2,000 pounds
1.5 tons = 3,000 pounds

After reducing the weight by 300 pounds,
the car now weighs

               (3,000 pounds)  -  (300 pounds)  =  2,700 pounds .

                                   (that's  2,700/2,000 =  1.35 tons)
