Hurry you
the tree diagram below shows all of the possible outcomes for flipping three coins.

a tree diagram has outcomes (h, h, h), (h, h, t), (h, t, h), (h, t, t), (t, h, h), (t, h, t), (t, t, h), (t, t, t).

what is the probability of one of the coins landing on tails and two of them landing on heads?
1/4
3/8
1/2
3/4

Probability of one of the coin landing on tails and two of them landing on heads is

Step-by-step explanation:

Given:-

Outcomes = (H, H, H), (H, H, T), (H, T, H), (H, T, T), (T, H, H), (T, H, T), (T, T, H), (T, T, T)

To find:- Probability of 1 coin landing on tails and 2 heads=?

Solution:-

Outcomes = (H, H, H), (H, H, T), (H, T, H), (H, T, T), (T, H, H), (T, H, T), (T, T, H), (T, T, T)

    ----------------(1)

Favourable outcomes = (H,H,T),(H,T,H),(T,H,H)

   ------------------(2)

Now using probability formula,

Probability of outcomes = No. of favourable outcomes / Total no. of possible outcomes

Probability of 1 tail and 2 heads =

Probability of 1 tail and 2 heads =

Probability of 1 tail and 2 heads =    ------(from 1 and 2)

Therefore probability of one of the coin landing on tails and two of them landing on heads is

idk this answer sorry cant on this one.

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
