<h3>The both events are <u>not independent</u> as the intersection of outcomes of both the events is 3  and  not equal to Ф.</h3>

Step-by-step explanation:

Here, the total number of cards in a deck = 52

The total number of heart cards  =  13

The total number of red faces in the deck  = 6 ( 3 of heart and 3 of diamonds)

Now, out of the TOTAL 6 red face cards, 3 are of hearts.

So, (Red cards) ∩ (Heart cards)  = 3 cards ( J, Q and K)

Now let E : Event of picking card which is of heart.

P(E) = \frac{\textrm{Total number of red hearts}}{\textrm{Total cards}}  = \frac{13}{52}  = (\frac{1}{4})

So, the probability of picking a heart = \frac{1}{4}

Now let F : Event of picking card which is of red face.

P(E) = \frac{\textrm{Total number of red faces}}{\textrm{Total cards}}  = \frac{6}{52}  = (\frac{3}{26})

So, the probability of picking a red face card  = \frac{3}{26}

Hence, the both events E and F are <u>not independent</u> as the intersection of outcomes of both the events is 3  and  not equal to \phi.

Answer:

$25.57

Step-by-step explanation:

First, you have to multiply $5.29 by 2 because she wants to spend $5.29 on 2 pairs of socks.

5.29 * 2 = $10.58

Then you want to add $10.58 and $14.99 together.

$10.58 + $14.99 = $25.57

The measure of one a cite angle of a right triangle is 6 less than twice the measure of the other acute angle find the measure o
jeka57 [31]

Answer:

32°, 58°

Step-by-step explanation:

Let one acute angle measure x.

The other acute angle measures 2x - 6.

The sum of the measures of the acute angles of a right triangle is 90.

x + 2x - 6 = 90

3x - 6 = 90

3x = 96

x = 32

2x - 6 = 2(32) - 6 = 58

Answer: 32°, 58°

Write each percent as a fraction in simplest form 16%
padilas [110]

Answer:

16% is 4/25 15% is 3/20 14% is 7/50 13% is 13/100 12% is 3/25 11% is 11/100 10% is 1/10 9% is 9/100 8% is 2/25 7% is 7/100 6% is 3/50 5% is 1/20 4% is 1/25 3% is 3/100 2% is 1/50 and 1% is 1/100

Step-by-step explanation:

If you want to find a percent you have to put that number over 100 so say I was looking for 20% you would put 20/100 then you would reduce by dividing if they can and both can be divided by two so it would then be 10/50 then those can be divided by 10 so it would be 1/5
