If one letter is chosen at random from word "combed" what is the probability that the letter chosen will be a "d"

It would be either 1/6 or 1:6.

Total letters = 6
Total d = 1

P(d) = 1/6

Answer : 1/6

Technically speaking, histograms are another version of bar charts, if you need to work one out then skim through google hope-o that -o!

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

0 = ( 2 - 4 ) ( p + q )0 = ( 2 - 4 ) ( 2 + 5 i ),   by multiplying these0 = ( 4 + 10 i - 8 - 20 i )0 = 4 - 8 + 10 i - 20 i0 = - 4 -10 i   0 = 2 ( - 2 - 5 i )0 / 2 = - 2 - 5 i- 2 - 5 i = 0- 5 i = 2i = 2 / - 5
