The probability that the spinner does not land on sector F or E is 25/36.
In the question, we are given that the central angle of sector E is 71° and the central angle of sector F is 39°.
We are asked for the probability that the spinner does not land on sector F or E.
The total central angle for a circle is 360°.
The probability of the spinner landing on sector E = 71°/360°.
The probability of the spinner landing on sector F = 39°/360°.
Thus, the probability of the spinner landing on sector F or E = 71°/360° + 39°/360° = 110°/360°.
Thus, the probability of the spinner not landing on sector F or E = 1 - 110°/360° = 250°/360° = 25/36.
Thus, the probability that the spinner does not land on sector F or E is 25/36.
