Moral of the story, never question what mothers think , because they just know! she definitely is right

It's a short Bio-statistics course , as a part of a postgraduate education , but math & statistics have always given me hard time hehe

You are a genius ! Thanks a lot .

Hello Bobbym,

Thank you for your quick reply ! i really appreciate it

the other part is

'at most 2 are malnourished' ?

there's another problem, it goes like

'The number of bacteria in culture growing by 16 each 4 days, in one day,

a) Find the probability of 2 growing bacterias

b) Find the probability of more than 3 growing bacteria '

i don't know what's up with me , but i can't seem to find my way around probabilities , & it's really devastating .
