The table shows the number of men and women who have entered a grocery store. What is the experimental probability that the next person to enter the store will be a man?
Outcome Men Women Frequency 30 25
Are you saying that 25 women and 30 men entered the store?
yes
Since 25 women entered the store, and 30 men entered the store, you can make a proportion. \[\frac{ 30 }{ 55 }\] 30 represent the men, and the 55 represent the total women and men. This shows you the probability of a man entering a store, 30/55. You can simplify it. \[\frac{ 30 }{ 55 } = \frac{ 6 }{ 11 }\] Answer: The probability of a man entering a store is a 6/11 chance.
5/6 ?
No, it's 6/11.
how?
Okay. There's 30 men. There's also 25 women. The denonimator represent the total outcome. 25 is not the total outcome, it's the amount of women that entered the store.
ohhhhh I got it, 25+30=55 & 30/55= 6/11
simplify. it.
Think about it. If there was 50 men and there's 5 women. Would you put it as 50/5 or 50/55?. 50/5 would mean there there's a 10/1 chance that there would be a men entering the store. (Which is impossible). 50/55 would simplify to 10/11. Which is reasonable.
very thanks
I hope this help. :)
