Abox contains five balls numbered 1, 2, 3, 4, 5. three balls are drawn randomly at the same time from the box.
(i) by listing all possible outcomes (123, 124, find the probability that the sum of the three numbers drawn is an odd number.
the random variable l denotes the largest of the three numbers drawn.
(ii) find the probability that l is 4.

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x
