Ok so first we need to distribute so:
<span>=<span><span><span><span><span>(4)</span><span>(b)</span></span>+<span><span>(4)</span><span>(2)</span></span></span>+</span>−<span>3b
</span></span></span>=<span>4b+8+−3b
</span>So now that we've distrubuted that we are now going to Combine Like Terms:
<span>=<span><span><span>4b</span>+8</span>+<span>−<span>3b
</span></span></span></span><span>=<span><span>(<span><span>4b</span>+<span>−<span>3b</span></span></span>)</span>+<span>(8)
Finally your answer is:
</span></span></span><span>=<span>b+<span>8
I hope this helps you!</span></span></span>

4 (b + 2 ) - 3b

............

Time to combine like terms.

...................

Which gives us ---> 1b + 8

A group of people were given a personality test to determine if they were Type A or Type B. The results are shown in the table b
amm1812

Answer:

Option A: P(Male or Type B) > P(Male | Type B)

Step-by-step explanation:

Total Female = 85 type A, 12 type B  ⇒ 97 Female.

Total Male = 65 type A, 38 type B   ⇒ 103 Male

Total type A = 65 + 85 = 150

Total type B = 12 + 38 = 50

total number of people = 97 + 103 = 200

Then the probability would be:

P(Male | Type B) = \frac{number of male in B}{total number of male}

                           = \frac{38}{103}

                           = 0.368

P(Male or Type B) = \frac{total number of male + (total number of people in B - total number of male in B)}{total number of male}

                              =  \frac{103 + (50 - 38)}{200}

                              = \frac{103 + 12}{200}

                              = \frac{115}{200}

                              = 0.575

 Hence, P(Male or Type B) > P(Male | Type B)
