Answer:
Step-by-step explanation:
6 symbols and 4-symbol code so number of combinations wich doesn't contain the same symbol twice would be:
6•5•4•3 = 360
If code starts with a star followed by triangle that means only one posibility for first two symbols and code doesn't containing the same symbol twice means that left 4 symbols for next two.
So number of combinations of code starting with a star followed by triangle and doesn't containing the same symbol twice will be:
1•1•4•3 = 12
The probability that a randomly chosen code starts with a star followed by triangle and doesn't contain the same symbol twice:
Answer:
60 miles per hour
Step-by-step explanation:
if you divide 360 by 6 you will get 60
To answer this question, we need o divide.
Since she has 1180 buttons, we can divide that number by the amount of buttons it takes to make a shirt, 6.
1180/6=196
