I dont understand question 7 because it says that it's a two digit number under 50 but out of a hundred and a hundred is a 3 digit number
ReplyDeletei agree with brandon if its suppose to be two digit then why is 100 in there also, when can we vome in for help with are homework if theres basketball in the morning?
ReplyDeleteI'm sorry folks. I don't have the textbook here. If you post the question I will help you with it. There is basketball in the morning, but I am at a workshop until 12pm tomorrow. I can help you after that.
ReplyDeleteMr. R.
thank you! the question is...a computer randumly chooses a 2 digit number between 1 and 100 what is the theritical possibility of each event
ReplyDeleteA:the num is less than 50
B: the num is even
C: the num is a multiple of 5
D: the ones digit of the num is greater than the tens digit
Larissa and others,
ReplyDeleteThe key word there is 'between'. Do not include 100 in your Total Possible Outcomes. How many possible outcomes are there between 1 and 100 that are two-digit, and how may favourable outcomes (outcomes you want) are there.
Hope this helps,
Mr. R.
thank you mr rumsby that help a lot i appreciate it!
ReplyDeletethank u mr.r
ReplyDeleteBLS
it says the probability of winning a game is 40%.predict how many times you expect to win in each situation.
ReplyDeletea)if you play 10 times
b)if you play 25 times
c)if you play 50 times
so would you take 40% and multiply it by 10 for a ) if not can you explain how to answer the question.

Lucy,
ReplyDeleteYes. You are trying to find 40% of 10, 25, and 50. Winning 40% of the time is the same as saying you have a probability of 40/100. Now, we just need to figure out how many times you'd win if you were playing only 10 times, etc.
HTH,
Mr. R.
