Answer: 1/4

Step-by-step explanation:

Probability= number of possible outcomes/ total number of outcomes

Therefore, if matrix tossed three coins at the same time,

Total outcomes will be ( HHH, HHT, HTH, THH, HTT, THT, TTH, TTT)

From the question, the possible outcomes of all three coins landing on the same side is HHH or TTT

Pr ( HHH, TTT) = 1/8 + 1/8

=2/8 = 1/4

I hope this is clear, please mark as brainliest answer.

OLga [1]

Answer:

21

ctto JBarnum

Step-by-step explanation:

P+11=(1/2)(P-13)^2

P+11=(1/2)(P^2-26p+169)

2(P+11)=(1/2)(2)(P^2-26p+169)

2P+22=P^2-26p+169

0=P^2-28p+147      ( -7 and -21)

(P-7)(P-21)=0

P=7,21                     (cant be 7 as 13 years from 7 is negative so peter is 21)

checking:

21+11=32

32=(1/2)(21-13)^2

32=(1/2)(8)^2

32=(1/2)64

32=32

correct
