Taylor surveys students in one grade level who own at least one pet. She finds that 50% of the students surveyed own 2 pets, 3 students own 3 pets each, and 2 students own 4 pets each. Eight of the students in the grade own 1 pet. Considering the number of pets as the random variable, x, which of the following is the probability distribution, px(x)? a probability distribution is shown. The probability of 1 is 0. 3; 2 is 0. 5; 3 is 0. 11; 4 is 0. 8. A probability distribution is shown. The probability of 1 is 0. 28; 2 is 0. 5; 3 is 0. 1; 4 is 0. 13. A probability distribution is shown. The probability of 1 is 0. 61; 2 is 0. 5; 3 is 0. 22; 4 is 0. 15. A probability distribution is shown. The probability of 1 is 0. 53; 2 is 0. 5; 3 is 0. 2; 4 is 0. 27.
