If there's 6 sectors, and each sector is equal, the probability of the spin landing into any sector has to be the same. Therefore, each sector should be equal to 1, or 1/6. If 4/6 are shaded, there's a 4/6 probability of the spin landing in a shaded sector.
A certain spinner is divided into 6 sectors of equal size, and the spinner is equally likely to land in any sector. Four of the 6 sectors are shaded, and the remaining sectors are not shaded.
Probability is the likelihood that an event will occur. Probability is a selection over the number of observation.
There are 4 shaded portion of the spinner and two unshaded portion.
The probability that when the spinner is spinned the portion will liand on four is simply
