Кидають три монети. Подія S1 полягає у тому, що на першій монеті випаде герб. Подія S2 полягає у том, що на другій монеті випаде герб. Скільки елементарних подій є сприятливими для появи події S1US2, тобто суми подій?

In the circuit below, R_1 = 10 Ω, R_2 = 11 Ω, R_3 = 13 Ω and R_4 = 29 Ω. Using this information, determine the total resistance of the circuit.
