Answer:
7 / 13
Step-by-step explanation:
The number of cards in a standard deck = 52
Number of red cards in a deck = 26
Number of queens in a deck = 4
Selecting a card at random ;
Probability of picking a red card ;
P(red card) = number of red cards / number of cards in deck
P(red card) = 26 / 52
P(queens card) = number of queens / number of cards in deck
P(queens card) = 4 / 52
Number of red queen cards = (red n queen) = 2
P(red or queens card) = P(red) + P(queens) - P(red n queen)
P(red or queens card) = 26/52 + 4/52 - 2/52
= (26 + 4 - 2) / 52
= 28 /52
= 7 / 13

Answer:
False.
Step-by-step explanation:
All the sides of an equilateral triangle are equal.
None of the sides of a scalene triangle are equal to each other.
Therefore, an equilateral triangle is <u>not</u><u> </u>similar to a scalene triangle.
Log (5) + log (3) = log (15)
Based on the total of intervals vs the number of intervals Amy attended her CA percentage is 75%
<h3>What is the CA percentage?</h3>
The CA percentage measures the commitment of an employee to be logged in during the intervals that were assigned to him/her to work.
In this way, the CA percentage is equal to 100% if the employee worked as scheduled. Moreover, this percentage can be affected by factors such as:
- Technical issues.
- Human errors.
In the case of Amy, there is a total of 12 intervals and it is known:
- She had a technical issue that prevented her from working, but this was reported so it is unlikely this is considered in her CA.
- She missed three intervals because she looked at her schedule wrong.
Based on this information, let's calculate her CA:
- 12 intervals = 100%
- 9 intervals = x
- x = 9 x 100 / 12
- x = 900 / 12
- x = 75%
