Answer:
1/221
Step-by-step explanation:
There are 4 kings in a standard deck of cards
P( one king) = number of kings/ number of cards
4/52
= 1/13
Then we do not put the card back. Now we have 3 kings and 51 cards
P(2nd king) = number of kings/ number of cards
=3/51
=1/17
We need to multiply these together
P( one king, 2nd king without replacement) = 1/13*1/17 = 1/221
Answer:
The probability that none of the three shoes selected are green = 64/125
Step-by-step explanation:
If we have 1/5 of shoes being green, then the number of non-green shoes = 1-1/5 = 4/5
Now, this is a probability with replacement.
probability of the first shoe since it’s not green = 4/5
probability of second shoes since it’s not green = 4/5
probability of third shoe since it’s not green = 4/5
Now, the probability that none of the shoes are green = 4/5 * 4/5 * 4/5 = 64/125

This is correct
Answer:
c = 6.1
Step-by-step explanation:
Given that: B = 18°
, C = 152°, and b = 4.
The missing side, c, can be determined by applying the sine rule which states that:
= 
= 
c = 
= 
= 6.0773
c = 6.1
Therefore, the value of the missing side, c, is 6.1
