Step-by-step explanation:
3000
Step-by-step explanation:
when you multiply by a ten (10, 100, 1000, etc.), just add a zero for each zero. it's the same when you divide: for every zero in the ten, you remove a zero.
There are ten combihations of the 5 boards taken 2 at a time. The values of x for each combination are as follows:
(1 ,2), x = 2; (1, 3), x = 1; (1,4), x = 1; (1, 5), x = 1; (2, 3), x = 1; (2, 4), x = 1; (2, 5), x = 1; (3,4), x = 0; (3, 5), x = 0; (4, 5), x = 0.
The mass function of x can be expressed as follows:
P(x = 0) = 0.3.
P(x = 1) = 0.6.
P(x = 2) = 0.1
