Probability of getting a multiple of 2&3 is 14/20.
14/20= 70%
Walt: assign probabilities to simple events using fractions and percentages.
This week I was learning to assign probabilities to a game played with 2
10 sided dice. I played with Rebecca. Our predict was to get a multiple of two and three. We alternated rolling the dice. We did this twenty times. We recorded our score in the outcomes column. Of the 20 attempts we were successful 14 times. So the probability is 14/20 as a simple fraction and as a percentage it is 70%. Since we played similar games this week I have a better understanding of assigning probabilities. Next I ‘d like to learn to add and subtract integers.
