Question

(!20 POINTS PLEASE HELP!) The students in a class are randomly drawing cards numbered 1 through 28 from a hat to determine the order in which they will give their presentations. Find each probability. Solve each problem below 1. P(13) 2. P(less than 14) 3. P(not 2 or 17)

Answer 1

Since there is 28 cards, the chance of drawing 1 card will be $\frac{1}{28}$

Therefore, $P(13)=\frac{1}{28}$.

There are 13 numbers less than 14 and greater than 0.

Therefore $P(>14)=\frac{13}{28}$

There are 26 numbers that are not 2 or 17.

Therefore $P(\neq 2,17)=\frac{26}{28}=\frac{13}{14}$

Hope this helps.

頑張って!

Answer 2

Probability of

Option (1). P(13) =$\frac{1}{28}$

Option (2). P(less than 14) = $\frac{13}{28}$

Option (3). P(not 2 or 17) =$\frac{13}{14}$

What is Probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur

Given,

Total number of card = 28

Probability = Number of favorable outcome / Number of total outcome

Probability of picking 13 = $\frac{1}{28}$

Probability of picking a card less then 14 = $\frac{13}{28}$

Probability of not picking 2 or 17 = $\frac{26}{28}=\frac{13}{14}$

Hence, the probability of

Option (1). P(13) =$\frac{1}{28}$

Option (2). P(less than 14) = $\frac{13}{28}$

Option (3). P(not 2 or 17) =$\frac{13}{14}$
