What is the probability of getting a total of at least 9 in a single throw of two dice?
10/36. One of the easier ways to find an answer is simply to make a table showing the possibilities of every move. 1 2 3 4 5 6 1| 2 3 4 5 6 7 2| 3 4 5 6 7 8 3| 4 5 6 7 8 9 4| 5 6 7 8 9 10 5| 6 7 8 9 10 11 6| 7 8 9 10 11 12 Based on the table, there are 36 different roll combinations, with a total of 10 combinations that are at lest 9.
What is the probability of getting 6 heads in 10 tosses of a fair coin?
(10C6)[P(H)^4][P(T)^6]= (210)[(1/2)^4][(1/2)^6]= (210)[(1/2)^10]= 0.205 In case you are not familiar with the notation, (10C6) means 10 choose 6. It is the number of way to pick 6 things from 10 when the order does not matter.We calculate this as 10C6 = 10!/[(10 - 6)!6!] = 10!/(4!6!) = (10 x 9 x 8 x 7x 6!)/(4 x 3 x 2 x 1 x 6!) simplify= 10 x 3 x 7 = 210
When two number cubes are rolled what is the probability that their sum will be 7?
There are a total of 36 outcomes. from 1,1; 1,2; .... to 6,5:6,6. For these to total '7' We have 1,6 ; 2,5 '; 3,4 ; 4,3 ; 5,2 ; & 6,1. There are six outcomes. So probability of a total of 7 ; P(total 7) = 6/36 = 1/6
What is the probability of spinning a multiple of 3 on a spinner labled 1 through 10?
To calculate the probability of spinning a multiple of 3 on a spinner labeled 1 through 10, we first determine the total number of favorable outcomes. The multiples of 3 between 1 and 10 are 3, 6, and 9. Therefore, there are 3 favorable outcomes. Since there are a total of 10 equally likely outcomes on the spinner, the probability of spinning a multiple of 3 is 3/10 or 0.3.
When two dice are rolled find the probability of getting a sum less than 10?
There are 36 combinations of two dice. each have 1 to 6To get 10 or more requires 4 +6, 5 +5, 5 +6 , 6+5, 6 +4, or 6+6, which are 6 combinations, leaving 36-6 = 30 combinations of less than 1030/36 = 5/6 probability of getting sum less than 10
