Một đồng xu được tung ba lần. a. Xây dựng không gian mẫu khi ta muốn quan sát tình trạng sấp ngửa của các lần tung.
b. Xây dựng không gian mẫu khi ta xem xét số lần ra mặt ngửa.

what are the answear choices to the question.

step-by-step explanation:

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

this is answer of 144 cubic meters
