Which of the following experiments could be used to simulate an event in which the probability of success, P (success), is 0.2 and the number of successes out of 10 events is desired?

Use a spinner that is divided into four equal parts. Let one color represent successful; the other three colors represent unsuccessful. Spin the spinner 10 times, once for each event.

Use a random number table, with digits 1 and 2 representing successful and the remaining digits representing unsuccessful. Choose 10 digits, one for each event.

Roll a die. Let 5 and 6 represent successful and the other values indicate unsuccessful. Roll the die 10 times, once for each event.

Count out 50 yellow beads and 50 pink beads. Select 10 of these beads at random. Let a yellow bead represent successful and a pink bead represent unsuccessful.
