Your answer would be the last option, 0.71.
To find the probability of the next pizza not being a cheese pizza, we need to find how many pizzas in the sample weren't cheese by adding them up. This gives us:
14 + 23 + 14 = 51
The total number of pizzas made is 21 + 14 + 23 + 14 = 72.
Therefore the probability of not making a cheese pizza would be 51/72 = 0.708 = 0.71
I hope this helps!
B) 64, because all these numbers have a difference of 14, and it you keep going, the 10th term will be 64.
If Daniel has two minutes and each game lasts for 15 seconds then he has eight tries to win. ( 120 seconds divided by 15 seconds = 8) And if his odds are .1 that means he has a 10% chance each game. 10% x 8 tries = 80% chance. or .8
