0.3
Step-by-step explanation:
Answer:
c. 0.05
Step-by-step explanation:
At the moment of the first selection, there are five possible gifts in total and only one umbrella among them, so the probability of choosing the umbrella is one fifth:
At the moment of the second selection, there are four possible gifts left and only one shaving kit among them, so the probability of choosing the kit is one fourth:
The probability of those two events happening in that order is its product:
P = P(A) · P(B) = 0.2 · 0.25 = 0.05
Breaking Apart Strategy is an easy way to find multiplication, even though those are difficult ones. This is a great strategy for breaking apart harder multiplication problems, so the result you get is the same as if you are multiplying the original equation.
<span>
For example, suppose you want to get this multiplication:
</span>
<span>
So eight times seven is a tricky one sometimes. Maybe we forget this multiplication so let's break it apart. Therefore, let's break apart seven, that is:
</span>
<span>
This is true because five and two makes seven. Therefore, the new equation is:
</span>
<span>
Applying distributive property:
</span>
<span>
So:
</span>
<span>As you can see the multiplication was obtained in a easy way.

Step-by-step explanation:
8t+1=17
8t=17-1
8t=16
t=2
12-4t=36
4t=12-36
4t=-24
t= -6
