Question

mario tagged a total of 147 squirrels. He tagged 38 tan male squirrels,10 tan female squirrels 82 gray male squirrels and 17 gray female squirrel.If this destribution accurately reflects the squirrel population what is the probability that the next squirrel mario captures will NOT be a gray squirrel

Answer 1

The chance that he will catch a grey squirrel is 

82/147

but you are trying to figure out the chance of him NOT getting a grey squirrel so

147/147 - 82 /147 = 65/147 

65/147 is your answer and you can not round that down anymore
