Answer:

11/16

Step-by-step explanation:

P(THHH)=4!3!∗(12)4=416P

(THHH)=4!3!∗(12)4=416, we are multiplying by 4!/3! since THHH scenario can occur in number of ways: THHH, HTHH , HHTH, or HHHT (notice that 4!/3! basically gives number of arrangements of 4 letters THHH out of which 3 H's are identcal).

P(T≥2)=1−(1/16+4/16)=11/16

Is radical 27 a rational or iffational number
ad-work [718]
Radical 27 is an irrational number and here's why.

Radical 27 can be simplified to 3 radical 3, or 3 times radical 3.
Since radical 3 is an irrational number, as you can see by typing it into a calculator, multiplying it by 3 would still result in a irrational number.

Hope this helps!
