Answer:

3 materials

Explanation:

The jacket and trousers worn by a firefighter have to be constructed from materials that will withstand intense heat. Aramid fiber is a synthetic fiber that is highly regarded for its strength and heat resistance. Nomex is the trade name for arimid fiber clothing, and this type of material is used in the construction of a firefighter jacket and trousers. Nomex is often combined with Kevlar to increase the strength of the material.

According to the general equation for conditional probability, if p (a^b')=1/6 and p(b')=7/12 , what is the value of p(a[b)?
Alex
P(B) = 1 - P(B') = 1 - (7/12) = 5/12 <span>P(A∩B)=<span><span>P(A∩<span>B′</span>)/</span><span>P(<span>B′</span>) </span></span>× <span><span>P(B)/</span>1

</span></span>Plugging values into the last equation we get: <span>P(A∩B)=<span><span>1×12×5 / </span><span>6×7×12 </span></span>= <span>542</span></span>
Now we can make use of the following formula <span>P(A|B)=<span><span>P(A∩B) / </span><span>P(B)</span></span></span><span> by plugging in the values that we have found.
</span>
<span>5/42 is the numerator and the denominator is 5/12.
</span>

The bottom (denominator) is P(B) which equals 5/12.

<span>P(A|B)=<span><span>5×12 / </span><span>42×5 = 6/210

6/210 = 2/7

</span></span></span><span>p(a[b]) = 2/7</span>
