Answer:


Step-by-step explanation:


I think you're making an incorrect assumption here. X and Y are two events based on two separate, independent series of coin tosses, from coins A and B, respectively. Here's an example:

Coin one:

T-T-T-T-H-H

Coin two:

H-H-H-T-T-T

<u><em>Event X (two heads in a row from coin A) occurred after event Y (three heads in a row from coin B). In the language of the question, X=6 and Y = 3. Since X>Y is a possible event in the space, P{X>Y} must be greater than zero.</em></u>

<em>answer:</em>

The problem can be broken down by the outcome of the first toss of the two coins.

Bearing arithmetic typos, the answer should be <u><em>43/58.</em></u>

<u><em>thanx</em></u>

<u><em>hope it helps youuu</em></u>

Sixty seven percent of the employees in a company have managerial positions, and 58 percent of the employees in the company have
Kazeer [188]

Answer: The proportion of employees who either have MBAs or are managers are 0.58.

Step-by-step explanation:

Since we have given that

Probability of employees having managerial positions = 67%

Probability of employees having MBA degrees = 58%

Probability of managers having MBA degrees = 67%

So, using probability formulas, we get that

P(A\cup B)=P(A)+P(B)-P(A\cap B)\\\\P(A\cup B)=0.67+0.58-0.67\\\\P(A\cup B)=0.58

Hence, the proportion of employees who either have MBAs or are managers are 0.58.

zavuch27 [327]

Answer:

3/6 or 1/2 (50%)

Step-by-step explanation:

There is 6 containers of each flavor, correct?

If you pick 3 of the same flavor, 3/6, it would look like that fraction.

If you simplify it, It'd be 1/2.

If you want it as a percent, It'd be 50%.

As a decimal, It's .50.
