Question

Use the spinner shown to answer the question Assume that it is equally probable that the pointer wil land on any one of the colored regions of the pointer lands on a borderline, spin agan If the spineris spun once, find the probability that the pointer lands in a region that is brown or blue brown red red yellow brown Ted

Answer 1

Given; Printere cam land any one of the cloured Region and there are four colours - 'Red, Brown, Blue and Yelloww. and Total 10 coloured Region. Let, Abe the event that pointer lands on Blue Region B be the event that pointed Lands on Yellow Region e be the event that pointer lands on Brown Region, I be the event that Pointor lands oh Red Region 3 P(e) = 10 Now, P (A) P(B) 2 10 2 10 oft vill 7 - ; P(D) = 3/20

On any one of the 10 Regions; Sinee, A pointer can land So, P(ANC) = 0 because Pointer Can't land Blue and Brown Region at a time. Now, cue lands have to find the Probablity that the pointer Region that is bosown on blue. P(AUC) P (A) +Ple) - P(ang) + 5/20 = 1/2 (Avs) 3 10 -0 2+3 10
