Given that there are three different games played.

Game 1: Toss a coin

Game 2: Drawing a letter at random from the alphabet

Game 3: Toss two coins


From first game we need to get "tail"

we know that there are two possible cases when tossing any coin {Head , Tail}

So probability of getting tail = 1/2


From second game we need to get letter "T"

we know that there are total 26 alphabets

So probability of getting letter T = 1/26


From third game we need to get two "tail"

Possible cases are {HH, HT, TH, TT} which are 4

H means Head T means tail. We see that double tail occurs only once from 4 possible cases

So probability of getting two tail = 1/4


Now we can combine all the results to find the probability of getting a tail, the letter T, and then two tails


Probability = \frac{1}{2}\cdot\frac{1}{26}\cdot\frac{1}{4} = \frac{1}{208}

Hence final answer will be \frac{1}{208}

Which graph represents the inequality 3y-5x&lt;-6? <br>​
nydimaria [60]

Answer:

First Graph

Step-by-step explanation:

3y-5x<-6

3y<5x-6

y<5/3x-6/3

y<5/3x-2

plug in the coordinates (0,0)

0<0-2

0<-2

0 is not less than -2

therefore the graph would be shaded opposite of (0,0)
