Answer:
1/16
Step-by-step explanation:
-1/4*-1/4
= -*- = +
= 1/4*1/4
=1/16
Answer:
Actual probability or experimental probability is the name of the "other" type of probability. We can always calculate in theory how an event will go: if you flip a coin twice, you should get one head and one tail. Yet in actuality, if you run an experiment you won't always get that theoretical result.

Answer:
(i) 0/7
(ii) 3/7
Step-by-step explanation:
In a deck of 52 playing cards, there are 13 cards of each clubs, spades, diamonds, and hearts. From those 13 cards, each group has 1 King, Queen, Jack respectively.
No.of total outcomes = 7
(i) In the entire 52 cards, there will be 4 Kings.
The probability of getting 4 kings in 7 cards can be 4/7.
But since there are only 4 kings (4<7), the probability of getting all kings in 7 cards would be 0/7.
Answer:
the probability that the rack ends up in alphabetical order is 0.0001984
Step-by-step explanation:
Given that:
You own 24 CDs. You want to randomly arrange 7 of them in a CD rack.
Th probability that the rack ends up in alphabetical order can be determined by taking note of the permutations and combinations.
From above; all possible permutations of size 7 we can derive from 24 is
24P7
Similarly,we are meant to estimate all the possible ways a unique set of 7 things can be gotten from a total of 24
i.e
24 C7
∴
The probability = 
= 
=
= 
= 0.0001984
the probability that the rack ends up in alphabetical order is 0.0001984
