Abag contains 25 marbles; 10 black,13 red, and 2 blue. a marble is drawn from the bag at random.
a.) explain why the events "getting a black marble" and "getting a red marble" are mutually exclusive.
b.)what is the probability of getting a red or a blue marble?
c.) a car approaching an intersection has a 0.1 probability of turning left and a 0.2 probability of turning right. explain why the events are mutually exclusive. what is the probability that the car will turn?

If jm equals 5x -8 and lm equals 2x -6 which expression represents jl

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
