How do you find the mean median and mode?
To find the mean you add all the numbers together then divide by how many there are. Ex. 5+10+6+6+5+12+5=49 49/7=7 Mean=7 To find the median you put the numbers from least to greatest the find the number in the middle. (note: if there are two numbers in the middle add hem and divide by two.) Ex. 5,5,5,6,6,10,12 Median:6 To find the mode you look for the number that appears the most. (note: There can be more than one mode or there can be no mode) Ex. 5,5,5,6,6,10,12 Mode:5
If 5 cards are drawn from a deck of cards without replacement What is the Probability that at least One of the cards is a heart?
P( at least one card is a heart) = 1 - P( 0 hearts) P(0 hearts) = (39/52)(38/51)(37/50)(36/49)(35/48) P( at least 1 heart) = 1- (39/52)(38/51)(37/50)(36/49)(35/48) =0.778466
If 4 cards are drawn from a deck of cards without replacement What is the probability that at least one of the cards is a heart?
It is 1 - prob(none of the four is a heart) = 1 - (39/52)*(38/51)*(37/50)*(36/49) = 1 - 1974024/6497400 = 0.6962
