Answer:
16
Step-by-step explanation:
Answer:1)Number of different license plates can be made =17576×100×260=456976000
2)Probability of getting a plate with abc123 or 123 abc=0.0000004
Given that :-A license plate has six characters.
As three characters are letters ∴ ways of these 3 letters into the plate with repetition = 26×26×26=17576 ways
and two characters are numbers (0-9 - total 10 characters)∴ways of these 2 numbers into the plate with repetition=10×10 =100 ways
and one character is a letter or a number=26×10=260
So number of different license plates can be made =17576×100×260=456976000
Now Probability of getting a plate with abc123 or 123 abc
=P(abc123 or 123abc)=P(abc123)+P(123abc)-P(abc123)×P(123abc)=1/456976000+1/456976000-1/456976000×1/456976000
=1/456976000(1+1-1/456976000)
=1/456976000(2-0.0000002)=2/456976000=0.0000004
Probability of getting a plate with abc123 or 123 abc=0.0000004
Step 1 associative property
step 2 subtract 2x from both sides
step 3 add 28 to both sides
step 4 divide 2 on both sides
Sure. From those choices, the only one that makes sense is that he
didn't perform enough trials. Technically, you can't expect the experimental
probability to match the theoretical probability until you've rolled it an infinite
number of times.
I have a hunch that even for only 60 trials, such a great discrepancy between
theory and experiment is beginning to suggest that the cubie is loaded. But
you really can't say. You just have to keep trying and watch how the numbers
add up.
