Alena has a pair of dogs, and she noticed they usually breed more male puppies than females. To check that, she bred them again and obtained 15 puppies, and 13 of them were males. Let's test the hypothesis that each puppy has an equal chance of 50% of being either male or female versus the alternative that the chance of a male puppy is greater. The table below sums up the results of 1000 simulations, each simulating 15 puppies with a 50%, percent chance of being male or female. According to the simulations, what is the probability of having 13 male puppies or more out of 15?

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer

93-8=85

855=17

17*4=68

there are 68 purple marbles in that bag

how many friends does he have? i think some of the information got cut off in the problem.

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
