Answer: 3/40

Step-by-step explanation:

Number of A's = 4

Number of B's = 5

Number of C's = 6

Number of D's = 5

Total number of letters tiles = 20

Probability of selecting C = 6/20 = 3/10

Probability of selecting D = 5/20 = 1/4

P( C and D)= 3/10 × 1/4 = 3/40

Answer:

between 3 and 4

Step-by-step explanation:

to find 19/6 located where on the number line

first we need to convert 19/6 to decimal

19/6 = 3.166...

so lets now see where 3.166 lies

it first lies between 3.160 and 3.170

but we need integer

so we go deeper and see

it lies between 3.100 and 3.200

and then we need to go more deeper to get an integer not decimal

now it lies between 3 and 4
