Timedthe table shows the results of a survey in which 10th-grade students were asked how many siblings (brothers and/or sisters) they have. what is the experimental probability that a 10th-grade student chosen at random has at least one, but no more than two, siblings? to the nearest whole percent, the experimental probability is a. 65%. b. 70% c. 75% d. 80%

We are given to find

the experimental probability that a 10th-grade student chosen at random has at least one, but no more than two, siblings

we know that

probability = ( number of favourable outcomes)/ ( total possible outcomes)

a 10th-grade student chosen at random has at least one, but no more than two, siblings

so, there can be one or two siblings

so, total number of such students =18+10=28

Number of favourable outcomes =28

total number of students =4+18+10+8=40

so, total favourable outcomes =40

now, we can find probability

So,

the experimental probability is 70%...........Answer

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

his chances of getting a coin of higher value is 4/19
