We are drawing two cards without replacement from a standard​ 52-card deck. find the probability that we draw at least one red c
alina1380 [7]
The probability of drawing only one red card in two draws without replacement is given by:
P(1\ red)=\frac{26C1\times26C1}{52C2}=0.51
The probability of drawing two red cards in two draws without replacement isgiven by:
P(2\ red)=\frac{26C2\times26C0}{52C2}=0.245
The events 'draw one red card' and 'draw two red cards' are mutually exclusive. Therefore the probability of drawing at least one red card is 0.51 + 0.245 = 0.755.

Multiple-Choice The average distance
murzikaleks [220]
Alright, so it would be helpful to think about this question in terms of units. You're given a distance (meters) and speed (meters per second). You're asked for time (which is in seconds).

If you do \frac{meters}{meters/second}, your answer will be in seconds. So divide your distance (2.28 x 10^11 meters) by your speed (3.00 x 10^8 meters/second), and you should get your time!

What is the difference in Fahrenheit degrees between a temperature of 0C and a temperature of 15C?
slamgirl [31]

Answer:

27^{\circ}F

Step-by-step explanation:

Use formula

F=1.8C+32

to convert Celsius to Fahrenheit.

When C_1=0^{\circ}C, then

F_1=1.8\cdot 0+32\\ \\F_1=32^{\circ}F

When C_2=15^{\circ}C, then

F_2=1.8\cdot 15+32\\ \\F_2=27+32=59^{\circ}F

Difference:

F_2-F_1=59^{\circ}F-32^{\circ}F=27^{\circ}F
