Answer:
1/12
Step-by-step explanation:
The probability of just picking up a 1 is 1/4 since there is only one 1 out of 4 total cards.
If you eliminate that 1 card, there are 3 cards left, and the probability of then picking a 4 becomes 1/3.
Multiplying these probabilities, we get 1/4 * 1/3 = 1/12 as the probability of picking up a 1, not returning it, and then picking a 4 afterward.
Answer:
754 logs
Step-by-step explanation:
If you are starting at 48 logs on the bottom row subtracting one log for each row you go up, then you should have 28 logs in the top row.
This is because 48-20=28
now you need to find the factorial of 48 starting at 28.
Factorial is like 1+2+3+4+5=15. So it is basically just adding every single whole number that are in between 2 whole numbers.
So for this equation you would need to do: 28+29+30+31+32+33+34+35+36+37+38+39+40+41+42+43+44+45+46+47+48= 754.
