What is the probability that a point chosen at random in the triangle is also in the blue square?
matrenka [14]

The <u>probability</u> that a point <u>chosen at random</u> in the triangle is also in the blue square can be calculated using <u>geometrical definition of the probability</u>:

Pr=\dfrac{\text{desired area}}{\text{total area}}.

1. Find the total area of the triangle:

A_{total}=\dfrac{1}{2}\cdot 6\cdot 9=27\ in^2.

2. Find the desired area of the square:

A_{desired}=3\cdot 3=9\ in^2.

Then the probability is

Pr=\dfrac{9}{27}=\dfrac{1}{3}.

Answer: correct choice is B

NEED HELP ASAP!!!
Sergeeva-Olga [200]

Answer:

(b) P(\textrm{Event of getting a 3 in the spinner)}  =  \frac{11}{61}

Step-by-step explanation:

Let E: Event of getting a 3 in the spinner.

So, the number of favorable outcomes  =  11

Total number of outcomes = Number of times the outcomes is {1,2,3,4,5,6}

= {13 +10 +11+16+11}  = { 61}

So, the total number of outcomes = 61

\textrm{Probability of Event E}  = \frac{\textrm{Number of favorable events}}{\textrm{Total number of outcomes}}

So, here P(\textrm{Event of getting a 3 in the spinner)}  =  \frac{11}{61}
