A four sided, balanced die has the values 1, 2, 3, and 4. There are three successive throws. Find the probability of throwing 1, 2, and 4 in any order
Hints: First throw: 3 choices (among 1,2 and 4) Second throw: 2 choices remaining Third throw: 1 choice remaining Success: 3*2*1 possibilities \(\Omega\): 4^3 possible outcomes.
So would you do 3/4 * 2/3 * 1/2? Or would you divide 6/64?
So would it be 3/4 * 2/4 * 1/4 since they are independent?
$$ 111\\ 112\\ 113\\ 114\\ 121\\ 122\\ 123\\ 124\\ 131\\ 132\\ 133\\ 134\\ ... $$
so we know there are 4*4*4 possible ways to list three integers from 1 to 4, since repetitions are allowed. Thus the denominator will be 4^3. For the numerator we have 3 ways to choose the first number, 2 ways for the second number, and 1 way for the last number. $$ \large \frac{3}{4} \cdot \frac{2}{4} \cdot \frac{1}{4}$$
Ahhh okay I understand.
so you can separate the problem into two parts. The numerator is counting how many ways you can rearrange 1,2,4 in any order 1,2,4 1,4,2 2,1,4 2,4,1 4,1,2 4,2,1
the denominator is how many ways you can count 1,1,1 1,1,2 1,1,3 , etc
So would the answer be 9.375%?
